Subject: [PATCH 09/35] "allow static get_rows callbacks, eg.
 'app_ui::get_rows': - on php5.3+ they get directly called via a variable:
 $callback($query,$rows,$readonlys) - on php < 5.3 we instancate the class, an
 call the method non-static: $obj->$method($query,$rows,$readonlys) --> allows
 application code to be prepared for static callbacks Note: - we can not use
 call_user_func, as it does NOT support passing by reverence, which is
 required for $rows and $readonlys parameter - static callbacks allow to NOT
 instanciate the class again for the callback (without current dirty methods
 like placing the object in $GLOBALS[$class])"

+Install
+    How to install HTML Purifier
+
+HTML Purifier is designed to run out of the box, so actually using the
+library is extremely easy.  (Although... if you were looking for a
+step-by-step installation GUI, you've downloaded the wrong software!)
+
+While the impatient can get going immediately with some of the sample
+code at the bottom of this library, it's well worth reading this entire
+document--most of the other documentation assumes that you are familiar
+with these contents.
+
+
+---------------------------------------------------------------------------
+1.  Compatibility
+
+HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and
+up. It has no core dependencies with other libraries. PHP
+4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0.
+
+These optional extensions can enhance the capabilities of HTML Purifier:
+
+    * iconv  : Converts text to and from non-UTF-8 encodings
+    * bcmath : Used for unit conversion and imagecrash protection
+    * tidy   : Used for pretty-printing HTML
+
+
+---------------------------------------------------------------------------
+2.  Reconnaissance
+
+A big plus of HTML Purifier is its inerrant support of standards, so
+your web-pages should be standards-compliant.  (They should also use
+semantic markup, but that's another issue altogether, one HTML Purifier
+cannot fix without reading your mind.)
+
+HTML Purifier can process these doctypes:
+
+* XHTML 1.0 Transitional (default)
+* XHTML 1.0 Strict
+* HTML 4.01 Transitional
+* HTML 4.01 Strict
+* XHTML 1.1
+
+...and these character encodings:
+
+* UTF-8 (default)
+* Any encoding iconv supports (with crippled internationalization support)
+
+These defaults reflect what my choices would be if I were authoring an
+HTML document, however, what you choose depends on the nature of your
+codebase.  If you don't know what doctype you are using, you can determine
+the doctype from this identifier at the top of your source code:
+
+    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
+        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
+
+...and the character encoding from this code:
+
+    <meta http-equiv="Content-type" content="text/html;charset=ENCODING">
+
+If the character encoding declaration is missing, STOP NOW, and
+read 'docs/enduser-utf8.html' (web accessible at
+http://htmlpurifier.org/docs/enduser-utf8.html).  In fact, even if it is
+present, read this document anyway, as many websites specify their
+document's character encoding incorrectly.
+
+
+---------------------------------------------------------------------------
+3.  Including the library
+
+The procedure is quite simple:
+
+    require_once '/path/to/library/HTMLPurifier.auto.php';
+
+This will setup an autoloader, so the library's files are only included
+when you use them.
+
+Only the contents in the library/ folder are necessary, so you can remove
+everything else when using HTML Purifier in a production environment.
+
+If you installed HTML Purifier via PEAR, all you need to do is:
+
+    require_once 'HTMLPurifier.auto.php';
+
+Please note that the usual PEAR practice of including just the classes you
+want will not work with HTML Purifier's autoloading scheme.
+
+Advanced users, read on; other users can skip to section 4.
+
+Autoload compatibility
+----------------------
+
+    HTML Purifier attempts to be as smart as possible when registering an
+    autoloader, but there are some cases where you will need to change
+    your own code to accomodate HTML Purifier. These are those cases:
+
+    PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
+        Because spl_autoload_register() doesn't exist in early versions
+        of PHP 5, HTML Purifier has no way of adding itself to the autoload
+        stack. Modify your __autoload function to test
+        HTMLPurifier_Bootstrap::autoload($class)
+
+        For example, suppose your autoload function looks like this:
+
+            function __autoload($class) {
+                require str_replace('_', '/', $class) . '.php';
+                return true;
+            }
+
+        A modified version with HTML Purifier would look like this:
+
+            function __autoload($class) {
+                if (HTMLPurifier_Bootstrap::autoload($class)) return true;
+                require str_replace('_', '/', $class) . '.php';
+                return true;
+            }
+
+        Note that there *is* some custom behavior in our autoloader; the
+        original autoloader in our example would work for 99% of the time,
+        but would fail when including language files.
+
+    AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
+        spl_autoload_register() has the curious behavior of disabling
+        the existing __autoload() handler. Users need to explicitly
+        spl_autoload_register('__autoload'). Because we use SPL when it
+        is available, __autoload() will ALWAYS be disabled. If __autoload()
+        is declared before HTML Purifier is loaded, this is not a problem:
+        HTML Purifier will register the function for you. But if it is
+        declared afterwards, it will mysteriously not work. This
+        snippet of code (after your autoloader is defined) will fix it:
+
+            spl_autoload_register('__autoload')
+
+    Users should also be on guard if they use a version of PHP previous
+    to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
+    for you, which can collide with an autoloader that was added by *you*
+    later.
+
+
+For better performance
+----------------------
+
+    Opcode caches, which greatly speed up PHP initialization for scripts
+    with large amounts of code (HTML Purifier included), don't like
+    autoloaders. We offer an include file that includes all of HTML Purifier's
+    files in one go in an opcode cache friendly manner:
+
+        // If /path/to/library isn't already in your include path, uncomment
+        // the below line:
+        // require '/path/to/library/HTMLPurifier.path.php';
+
+        require 'HTMLPurifier.includes.php';
+
+    Optional components still need to be included--you'll know if you try to
+    use a feature and you get a class doesn't exists error! The autoloader
+    can be used in conjunction with this approach to catch classes that are
+    missing. Simply add this afterwards:
+
+        require 'HTMLPurifier.autoload.php';
+
+Standalone version
+------------------
+
+    HTML Purifier has a standalone distribution; you can also generate
+    a standalone file from the full version by running the script
+    maintenance/generate-standalone.php . The standalone version has the
+    benefit of having most of its code in one file, so parsing is much
+    faster and the library is easier to manage.
+
+    If HTMLPurifier.standalone.php exists in the library directory, you
+    can use it like this:
+
+        require '/path/to/HTMLPurifier.standalone.php';
+
+    This is equivalent to including HTMLPurifier.includes.php, except that
+    the contents of standalone/ will be added to your path. To override this
+    behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
+    be found (usually, this will be one directory up, the "true" library
+    directory in full distributions). Don't forget to set your path too!
+
+    The autoloader can be added to the end to ensure the classes are
+    loaded when necessary; otherwise you can manually include them.
+    To use the autoloader, use this:
+
+        require 'HTMLPurifier.autoload.php';
+
+For advanced users
+------------------
+
+    HTMLPurifier.auto.php performs a number of operations that can be done
+    individually. These are:
+
+        HTMLPurifier.path.php
+            Puts /path/to/library in the include path. For high performance,
+            this should be done in php.ini.
+
+        HTMLPurifier.autoload.php
+            Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
+
+    You can do these operations by yourself--in fact, you must modify your own
+    autoload handler if you are using a version of PHP earlier than PHP 5.1.2
+    (See "Autoload compatibility" above).
+
+
+---------------------------------------------------------------------------
+4. Configuration
+
+HTML Purifier is designed to run out-of-the-box, but occasionally HTML
+Purifier needs to be told what to do.  If you answer no to any of these
+questions, read on; otherwise, you can skip to the next section (or, if you're
+into configuring things just for the heck of it, skip to 4.3).
+
+* Am I using UTF-8?
+* Am I using XHTML 1.0 Transitional?
+
+If you answered no to any of these questions, instantiate a configuration
+object and read on:
+
+    $config = HTMLPurifier_Config::createDefault();
+
+
+4.1. Setting a different character encoding
+
+You really shouldn't use any other encoding except UTF-8, especially if you
+plan to support multilingual websites (read section three for more details).
+However, switching to UTF-8 is not always immediately feasible, so we can
+adapt.
+
+HTML Purifier uses iconv to support other character encodings, as such,
+any encoding that iconv supports <http://www.gnu.org/software/libiconv/>
+HTML Purifier supports with this code:
+
+    $config->set('Core', 'Encoding', /* put your encoding here */);
+
+An example usage for Latin-1 websites (the most common encoding for English
+websites):
+
+    $config->set('Core', 'Encoding', 'ISO-8859-1');
+
+Note that HTML Purifier's support for non-Unicode encodings is crippled by the
+fact that any character not supported by that encoding will be silently
+dropped, EVEN if it is ampersand escaped.  If you want to work around
+this, you are welcome to read docs/enduser-utf8.html for a fix,
+but please be cognizant of the issues the "solution" creates (for this
+reason, I do not include the solution in this document).
+
+
+4.2. Setting a different doctype
+
+For those of you using HTML 4.01 Transitional, you can disable
+XHTML output like this:
+
+    $config->set('HTML', 'Doctype', 'HTML 4.01 Transitional');
+
+Other supported doctypes include:
+
+    * HTML 4.01 Strict
+    * HTML 4.01 Transitional
+    * XHTML 1.0 Strict
+    * XHTML 1.0 Transitional
+    * XHTML 1.1
+
+
+4.3. Other settings
+
+There are more configuration directives which can be read about
+here: <http://htmlpurifier.org/live/configdoc/plain.html>  They're a bit boring,
+but they can help out for those of you who like to exert maximum control over
+your code.  Some of the more interesting ones are configurable at the
+demo <http://htmlpurifier.org/demo.php> and are well worth looking into
+for your own system.
+
+For example, you can fine tune allowed elements and attributes, convert
+relative URLs to absolute ones, and even autoparagraph input text! These
+are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
+%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
+translates to:
+
+    $config->set('Namespace', 'Directive', $value);
+
+E.g.
+
+    $config->set('HTML', 'Allowed', 'p,b,a[href],i');
+    $config->set('URI', 'Base', 'http://www.example.com');
+    $config->set('URI', 'MakeAbsolute', true);
+    $config->set('AutoFormat', 'AutoParagraph', true);
+
+
+---------------------------------------------------------------------------
+5. Caching
+
+HTML Purifier generates some cache files (generally one or two) to speed up
+its execution. For maximum performance, make sure that
+library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
+
+If you are in the library/ folder of HTML Purifier, you can set the
+appropriate permissions using:
+
+    chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
+
+If the above command doesn't work, you may need to assign write permissions
+to all. This may be necessary if your webserver runs as nobody, but is
+not recommended since it means any other user can write files in the
+directory. Use:
+
+    chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
+
+You can also chmod files via your FTP client; this option
+is usually accessible by right clicking the corresponding directory and
+then selecting "chmod" or "file permissions".
+
+Starting with 2.0.1, HTML Purifier will generate friendly error messages
+that will tell you exactly what you have to chmod the directory to, if in doubt,
+follow its advice.
+
+If you are unable or unwilling to give write permissions to the cache
+directory, you can either disable the cache (and suffer a performance
+hit):
+
+    $config->set('Core', 'DefinitionCache', null);
+
+Or move the cache directory somewhere else (no trailing slash):
+
+    $config->set('Cache', 'SerializerPath', '/home/user/absolute/path');
+
+
+---------------------------------------------------------------------------
+6.   Using the code
+
+The interface is mind-numbingly simple:
+
+    $purifier = new HTMLPurifier();
+    $clean_html = $purifier->purify( $dirty_html );
+
+...or, if you're using the configuration object:
+
+    $purifier = new HTMLPurifier($config);
+    $clean_html = $purifier->purify( $dirty_html );
+
+That's it!  For more examples, check out docs/examples/ (they aren't very
+different though).  Also, docs/enduser-slow.html gives advice on what to
+do if HTML Purifier is slowing down your application.
+
+
+---------------------------------------------------------------------------
+7.   Quick install
+
+First, make sure library/HTMLPurifier/DefinitionCache/Serializer is
+writable by the webserver (see Section 5: Caching above for details).
+If your website is in UTF-8 and XHTML Transitional, use this code:
+
+<?php
+    require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
+
+    $purifier = new HTMLPurifier();
+    $clean_html = $purifier->purify($dirty_html);
+?>
+
+If your website is in a different encoding or doctype, use this code:
+
+<?php
+    require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
+
+    $config = HTMLPurifier_Config::createDefault();
+    $config->set('Core', 'Encoding', 'ISO-8859-1'); // replace with your encoding
+    $config->set('HTML', 'Doctype', 'HTML 4.01 Transitional'); // replace with your doctype
+    $purifier = new HTMLPurifier($config);
+
+    $clean_html = $purifier->purify($dirty_html);
+?>

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+    ! Feature
+    - Bugfix
+      + Sub-comment
+    . Internal change
+==========================
+
+3.3.0, released 2009-02-16
+! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
+! Implement generic property list classess
+- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
+  does not do the "right thing" with characters not supported in the output
+  set.
+- Spellcheck UTF-8: The Secret To Character Encoding
+- Fix improper removal of the contents of elements with only whitespace. Thanks
+  Eric Wald for reporting.
+- Fix broken test suite in versions of PHP without spl_autoload_register()
+- Fix degenerate case with YouTube filter involving double hyphens.
+  Thanks Pierre Attar for reporting.
+- Fix YouTube rendering problem on certain versions of Firefox.
+- Fix CSSDefinition Printer problems with decorators
+- Add text parameter to unit tests, forces text output
+. Add verbose mode to command line test runner, use (--verbose)
+. Turn on unit tests for UnitConverter
+. Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
+. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
+  tested on Linux.
+. Removed trailing whitespace from all text files, see
+  remote-trailing-whitespace.php maintenance script.
+. Convert configuration to use property list backend.
+
+3.2.0, released 2008-10-31
+# Using %Core.CollectErrors forces line number/column tracking on, whereas
+  previously you could theoretically turn it off.
+# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
+  use handleEnd() instead.
+! %Output.AttrSort for when you need your attributes in alphabetical order to
+  deal with a bug in FCKEditor. Requested by frank farmer.
+! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
+! Proper support for name attribute. It is now allowed and equivalent to the id
+  attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
+  is heavy (for all doctypes).
+! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
+  use on hand-written HTML.
+! Add error-cases for unsupported elements in MakeWellFormed. This enables
+  the strategy to be used, standalone, on untrusted input.
+! %Core.AggressivelyFixLt is on by default. This causes more sensible
+  processing of left angled brackets in smileys and other whatnot.
+! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
+  'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
+  the --only-phpt parameter, although for backwards-compatibility the flag
+  will still work.
+! AutoParagraph auto-formatter will now preserve double-newlines upon output.
+  Users who are not performing inbound filtering, this may seem a little
+  useless, but as a bonus, the test suite and handling of edge cases is also
+  improved.
+! Experimental implementation of forms for %HTML.Trusted
+! Track column numbers when maintain line numbers is on
+! Proprietary 'background' attribute on table-related elements converted into
+  corresponding CSS.  Thanks Fusemail for sponsoring this feature!
+! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
+  supertype.
+! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
+  time of operation varies slightly from notifyEnd() as *all* end tokens are
+  processed by the injector before they are subject to the well-formedness rules.
+! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
+  basename of image when not present.
+! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
+- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
+  the other involving an undefined $is_folder error.
+- Throw error when %Core.Encoding is set to a spurious value. Previously,
+  this errored silently and returned false.
+- Redirected stderr to stdout for flush error output.
+- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
+  available.
+- Do not re-munge URL if the output URL has the same host as the input URL.
+  Requested by Chris.
+- Fix error in documentation regarding %Filter.ExtractStyleBlocks
+- Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
+- Fix bug with inline elements in blockquotes conflicting with strict doctype
+- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
+- Fix bug where dots and double-dots in absolute URLs without hostname were
+  not collapsed by URIFilter_MakeAbsolute.
+- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
+  by reordering their addition.
+- Will now throw exception on many error conditions during lexer creation; also
+  throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
+  is being used.
+- Detect if domxml extension is loaded, and use DirectLEx accordingly.
+- Improve handling of big numbers with floating point arithmetic in UnitConverter.
+  Reported by David Morton.
+. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
+  for more interesting filter-backtracking
+. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
+  index to reprocess tokens.
+. StringHashParser now allows for multiline sections with "empty" content;
+  previously the section would remain undefined.
+. Added --quick option to multitest.php, which tests only the most recent
+  release for each series.
+. Added --distro option to multitest.php, which accepts either 'normal' or
+  'standalone'. This supercedes --exclude-normal and --exclude-standalone
+
+3.1.1, released 2008-06-19
+# %URI.Munge now, by default, does not munge resources (for example, <img src="">)
+  In order to enable this again, please set %URI.MungeResources to true.
+! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
+  and height/width HTML with %HTML.MaxImgLength.
+! %URI.MungeSecretKey for secure URI munging. Thanks Chris
+  for sponsoring this feature. Check out the corresponding documentation
+  for details. (Att Nightly testers: The API for this feature changed before
+  the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
+  %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
+! Implemented post URI filtering. Set member variable $post to true to set
+  a URIFilter as such.
+! Allow modules to define injectors via $info_injector. Injectors are
+  automatically disabled if injector's needed elements are not found.
+! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
+  Thanks Chris for sponsoring. If you've been using ad hoc code from the
+  forums, PLEASE use this instead.
+! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
+  embedded, tag name, attribute name, CSS property name). See %URI.Munge
+  for more details. Requested by Jochem Blok.
+- Disable percent height/width attributes for img.
+- AttrValidator operations are now atomic; updates to attributes are not
+  manifest in token until end of operations. This prevents naughty internal
+  code from directly modifying CurrentToken when they're not supposed to.
+  This semantics change was requested by frank farmer.
+- Percent encoding checks enabled for URI query and fragment
+- Fix stray backslashes in font-family; CSS Unicode character escapes are
+  now properly resolved (although *only* in font-family). Thanks Takeshi Terada
+  for reporting.
+- Improve parseCDATA algorithm to take into account newline normalization
+- Account for browser confusion between Yen character and backslash in
+  Shift_JIS encoding. This fix generalizes to any other encoding which is not
+  a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
+- Fix missing configuration parameter in Generator calls. Thanks vs for the
+  partial patch.
+- Improved adherence to Unicode by checking for non-character codepoints.
+  Thanks Geoffrey Sneddon for reporting. This may result in degraded
+  performance for extremely large inputs.
+- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
+  for reporting.
+. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
+  handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
+  this class.
+. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
+  to __construct($min, $max). __construct(true) is equivalent to
+  __construct('0').
+. Added HTMLPurifier_AttrDef_Switch class
+. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
+  up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
+  get this called with the configuration object.  All modules now
+  use this rather than __construct(), although legacy code using constructors
+  will still work--the new format, however, lets modules access the
+  configuration object for HTML namespace dependant tweaks.
+. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
+. ConfigSchema data-structure heavily optimized; on average it uses a third
+  the memory it did previously. The interface has changed accordingly,
+  consult changes to HTMLPurifier_Config for details.
+. Variable parsing types now are magic integers instead of strings
+. Added benchmark for ConfigSchema
+. HTMLPurifier_Generator requires $config and $context parameters. If you
+  don't know what they should be, use HTMLPurifier_Config::createDefault()
+  and new HTMLPurifier_Context().
+. Printers now properly distinguish between output configuration, and
+  target configuration. This is not applicable to scripts using
+  the Printers for HTML Purifier related tasks.
+. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
+  fatal errors will ensue.
+. URIFilter->prepare can return false in order to abort loading of the filter
+. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
+  an external resource.
+. %URI.Munge functionality factored out into a post-filter class.
+. Added CurrentCSSProperty context variable during CSS validation
+
+3.1.0, released 2008-05-18
+# Unnecessary references to objects (vestiges of PHP4) removed from method
+  signatures.  The following methods do not need references when assigning from
+  them and will result in E_STRICT errors if you try:
+    + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
+    + HTMLPurifier_ConfigSchema::instance()
+    + HTMLPurifier_DefinitionCacheFactory::instance()
+    + HTMLPurifier_DefinitionCacheFactory->create()
+    + HTMLPurifier_DoctypeRegistry->register()
+    + HTMLPurifier_DoctypeRegistry->get()
+    + HTMLPurifier_HTMLModule->addElement()
+    + HTMLPurifier_HTMLModule->addBlankElement()
+    + HTMLPurifier_LanguageFactory::instance()
+# Printer_ConfigForm's get*() functions were static-ified
+# %HTML.ForbiddenAttributes requires attribute declarations to be in the
+  form of tag@attr, NOT tag.attr (which will throw an error and won't do
+  anything). This is for forwards compatibility with XML; you'd do best
+  to migrate an %HTML.AllowedAttributes directives to this syntax too.
+! Allow index to be false for config from form creation
+! Added HTMLPurifier::VERSION constant
+! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
+  and allows for version numbers like "3.1.0-dev".
+! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
+! HTML Purifier's URI handling is a lot more robust, with much stricter
+  validation checks and better percent encoding handling. Thanks Gareth Heyes
+  for indicating security vulnerabilities from lax percent encoding.
+! Bootstrap autoloader deals more robustly with classes that don't exist,
+  preventing class_exists($class, true) from barfing.
+- InterchangeBuilder now alphabetizes its lists
+- Validation error in configdoc output fixed
+- Iconv and other encoding errors muted even with custom error handlers that
+  do not honor error_reporting
+- Add protection against imagecrash attack with CSS height/width
+- HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
+- Fixed and revamped broken ConfigForm smoketest
+- Bug with bool/null fields in Printer_ConfigForm fixed
+- Bug with global forbidden attributes fixed
+- Improved error messages for allowed and forbidden HTML elements and attributes
+- Missing (or null) in configdoc documentation restored
+- If DOM throws and exception during parsing with PH5P (occurs in newer versions
+  of DOM), HTML Purifier punts to DirectLex
+- Fatal error with unserialization of ScriptRequired
+- Created directories are now chmod'ed properly
+- Fixed bug with fallback languages in LanguageFactory
+- Standalone testing setup properly with autoload
+. Out-of-date documentation revised
+. UTF-8 encoding check optimization as suggested by Diego
+. HTMLPurifier_Error removed in favor of exceptions
+. More copy() function removed; should use clone instead
+. More extensive unit tests for HTMLDefinition
+. assertPurification moved to central harness
+. HTMLPurifier_Generator accepts $config and $context parameters during
+  instantiation, not runtime
+. Double-quotes outside of attribute values are now unescaped
+
+3.1.0rc1, released 2008-04-22
+# Autoload support added. Internal require_once's removed in favor of an
+  explicit require list or autoloading. To use HTML Purifier,
+  you must now either use HTMLPurifier.auto.php
+  or HTMLPurifier.includes.php; setting the include path and including
+  HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
+  as well to register our autoload handler (or modify your autoload function
+  to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
+  HTMLPurifier.safe-includes.php for a less performance friendly but more
+  user-friendly library load.
+# HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
+  information is stored in the ConfigSchema directory, and the
+  maintenance/generate-schema-cache.php generates the schema.ser file, which
+  is now instantiated. Support for userland schema changes coming soon!
+# HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
+  alias; to get rid of these errors just modify your configuration to use
+  the new directive name.
+# HTMLPurifier->addFilter is deprecated; built-in filters can now be
+  enabled using %Filter.$filter_name or by setting your own filters using
+  %Filter.Custom
+# Directive-level safety properties superceded in favor of module-level
+  safety. Internal method HTMLModule->addElement() has changed, although
+  the externally visible HTMLDefinition->addElement has *not* changed.
+! Extra utility classes for testing and non-library operations can
+  be found in extras/. Specifically, these are FSTools and ConfigDoc.
+  You may find a use for these in your own project, but right now they
+  are highly experimental and volatile.
+! Integration with PHPT allows for automated smoketests
+! Limited support for proprietary HTML elements, namely <marquee>, sponsored
+  by Chris. You can enable them with %HTML.Proprietary if your client
+  demands them.
+! Support for !important CSS cascade modifier. By default, this will be stripped
+  from CSS, but you can enable it using %CSS.AllowImportant
+! Support for display and visibility CSS properties added, set %CSS.AllowTricky
+  to true to use them.
+! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
+  Developer error (not enduser error) can cause these to be triggered.
+! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
+! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
+  mucking around with HTMLPurifier_CSSDefinition
+! ConfigDoc output has been enhanced with version and deprecation info.
+! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
+- Autoclose now operates iteratively, i.e. <span><span><div> now has
+  both span tags closed.
+- Various HTMLPurifier_Config convenience functions now accept another parameter
+  $schema which defines what HTMLPurifier_ConfigSchema to use besides the
+  global default.
+- Fix bug with trusted script handling in libxml versions later than 2.6.28.
+- Fix bug in ExtractStyleBlocks with comments in style tags
+- Fix bug in comment parsing for DirectLex
+- Flush output now displayed when in command line mode for unit tester

+  on the same element without emitting errors.
+- Fixed fatal error in PH5P lexer with invalid tag names
+. Plugins now get their own changelogs according to project conventions.
+. Convert tokens to use instanceof, reducing memory footprint and
+  improving comparison speed.
+. Dry runs now supported in SimpleTest; testing facilities improved
+. Bootstrap class added for handling autoloading functionality
+. Implemented recursive glob at FSTools->globr
+. ConfigSchema now has instance methods for all corresponding define*
+  static methods.
+. A couple of new historical maintenance scripts were added.
+. HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
+. tests/index.php can now be run from any directory.
+. HTMLPurifier_Token subclasses split into seperate files
+. HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
+. HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
+. New --php=php flag added, allows PHP executable to be specified (command
+  line only!)
+. htmlpurifier_add_test() preferred method to translate test files in to
+  classes, because it handles PHPT files too.
+. Debugger class is deprecated and will be removed soon.
+. Command line argument parsing for testing scripts revamped, now --opt value
+  format is supported.
+. Smoketests now cleanup after magic quotes
+. Generator now can output comments (however, comments are still stripped
+  from HTML Purifier output)
+. HTMLPurifier_ConfigSchema->validate() deprecated in favor of

+. When --flush fails in unit testers, abort tests and print message
+. Improved documentation in docs/dev-flush.html about the maintenance scripts
+. copy() methods removed in favor of clone keyword
+
+3.0.0, released 2008-01-06
+# HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
+  until PHP 4 is completely deprecated, but no new features will be added
+  to it.
+  + Visibility declarations added
+  + Constructor methods renamed to __construct()
+  + PHP4 reference cruft removed (in progress)
+! CSS properties are now case-insensitive
+! DefinitionCacheFactory now can register new implementations
+! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
+  documents and cleaning their contents up. Requires the CSSTidy library
+  <http://csstidy.sourceforge.net/>. You can access the blocks with the
+  'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
+  The output CSS can also be "scoped" for a specific element, use:
+  %Filter.ExtractStyleBlocksScope
+! Experimental support for some proprietary CSS attributes allowed:
+  opacity (and all of the browser-specific equivalents) and scrollbar colors.
+  Enable by setting %CSS.Proprietary to true.
+- Colors missing # but in hex form will be corrected
+- CSS Number algorithm improved
+- Unit testing and multi-testing now on steroids: command lines,
+  XML output, and other goodies now added.
+. Unit tests for Injector improved
+. New classes:

+. Multitest now has a file docblock
+
+2.1.3, released 2007-11-05
+! tests/multitest.php allows you to test multiple versions by running
+  tests/index.php through multiple interpreters using `phpv` shell

+- Injector algorithm further refined: off-by-one error regarding skip
+  counts for dormant injectors fixed
+- Corrective blockquote definition now enabled for HTML 4.01 Strict
+- Fatal error when <img> tag (or any other element with required attributes)
+  has 'id' attribute fixed, thanks NykO18 for reporting
+- Fix warning emitted when a non-supported URI scheme is passed to the
+  MakeAbsolute URIFilter, thanks NykO18 (again)
+- Further refine AutoParagraph injector. Behavior inside of elements
+  allowing paragraph tags clarified: only inline content delimeted by
+  double newlines (not block elements) are paragraphed.
+- Buggy treatment of end tags of elements that have required attributes
+  fixed (does not manifest on default tag-set)
+- Spurious internal content reorganization error suppressed
+- HTMLDefinition->addElement now returns a reference to the created
+  element object, as implied by the documentation
+- Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
+- Fix a theoretical class of infinite loops from DirectLex reported
+  by Nate Abele
+- Work around unnecessary DOMElement type-cast in PH5P that caused errors
+  in PHP 5.1
+- Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
+  HTMLDefinition errors, this may indicate problems with error-collecting
+  facilities in PHP 5

+- Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
+. %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
+  to better communicate its purpose

+
+2.1.2, released 2007-09-03
+! Implemented Object module for trusted users
+! Implemented experimental HTML5 parsing mode using PH5P. To use, add
+  this to your code:
+        require_once 'HTMLPurifier/Lexer/PH5P.php';
+        $config->set('Core', 'LexerImpl', 'PH5P');
+  Note that this Lexer introduces some classes not in the HTMLPurifier
+  namespace.  Also, this is PHP5 only.
+! CSS property border-spacing implemented
+- Fix non-visible parsing error in DirectLex with empty tags that have
+  slashes inside attribute values.
+- Fix typo in CSS definition: border-collapse:seperate; was incorrectly
+  accepted as valid CSS. Usually non-visible, because this styling is the
+  default for tables in most browsers. Thanks Brett Zamir for pointing
+  this out.
+- Fix validation errors in configuration form

+
+2.1.0, released 2007-08-02
+# flush-htmldefinition-cache.php superseded in favor of a generic
+  flush-definition-cache.php script, you can clear a specific cache
+  by passing its name as a parameter to the script
+! Phorum mod implemented for HTML Purifier
+! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
+  trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
+  for PHP4 (DirectLex).
+! Standalone file now available, which greatly reduces the amount of
+  includes (although there are still a few files that reside in the
+  standalone folder)
+! Relative URIs can now be transformed into their absolute equivalents
+  using %URI.Base and %URI.MakeAbsolute

+. Introduce new text/itext configuration directive values: these represent
+  longer strings that would be more appropriately edited with a textarea
+. Allow newlines to act as separators for lists, hashes, lookups and
+  %HTML.Allowed
+. ConfigForm generates textareas instead of text inputs for lists, hashes,
+  lookups, text and itext fields

+  be used to customize this behavior, by default <script> and <style> are
+  hidden
+. Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
+. Custom ChildDef added to default include list
+. URIScheme reflection improved: will not attempt to include file if class
+  already exists. May clobber autoload, so I need to keep an eye on it
+. ConfigSchema heavily optimized, will only collect information and validate
+  definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
+. AttrDef_URI unit tests and implementation refactored
+. benchmarks/ directory now protected from public view with .htaccess file;

+2.0.1, released 2007-06-27
+! Tag auto-closing now based on a ChildDef heuristic rather than a
+  manually set auto_close array; some behavior may change
+! Experimental AutoFormat functionality added: auto-paragraph and
+  linkify your HTML input by setting %AutoFormat.AutoParagraph and
+  %AutoFormat.Linkify to true
+! Newlines normalized internally, and then converted back to the
+  value of PHP_EOL. If this is not desired, set your newline format
+  using %Output.Newline.
+! Beta error collection, messages are implemented for the most generic
+  cases involving Lexing or Strategies
+- Clean up special case code for <script> tags
+- Reorder includes for DefinitionCache decorators, fixes a possible
+  missing class error

+  much easier selective embedding of configuration values
+. Doctype objects now accept public and system DTD identifiers
+. %HTML.Doctype is now constrained by specific values, to specify a custom
+  doctype use new %HTML.CustomDoctype
+. ConfigForm truncates long directives to keep the form small, and does
+  not re-output namespaces
+

+# Completely refactored HTMLModuleManager, decentralizing safety
+  information
+# Transform modules changed to Tidy modules, which offer more flexibility
+  and better modularization
+# Configuration object now finalizes itself when a read operation is
+  performed on it, ensuring that its internal state stays consistent.
+  To revert this behavior, you can set the $autoFinalize member variable
+  off, but it's not recommended.
+# New compact syntax for AttrDef objects that can be used to instantiate
+  new objects via make()
+# Definitions (esp. HTMLDefinition) are now cached for a significant
+  performance boost. You can disable caching by setting %Core.DefinitionCache

+# Contents between <script> tags are now completely removed if <script>
+  is not allowed
+# Prototype-declarations for Lexer removed in favor of configuration
+  determination of Lexer implementations.

+- Merging in attribute lists now works.
+. Demo script removed: it has been added to the website's repository
+. Basic.php script modified to work out of the box
+. Refactor AttrTransform classes to reduce duplication

+
+1.6.0, released 2007-04-01
+! Support for most common deprecated attributes via transformations:
+  + bgcolor in td, th, tr and table
+  + border in img
+  + name in a and img
+  + width in td, th and hr
+  + height in td, th
+! Support for CSS attribute 'height' added

+- You can define ID blacklists using regular expressions via
+  %Attr.IDBlacklistRegexp
+- Error messages are emitted when you attempt to "allow" elements or
+  attributes that HTML Purifier does not support
+- Fix segfault in unit test. The problem is not very reproduceable and
+  I don't know what causes it, but a six line patch fixed it.
+
+1.5.0, released 2007-03-23
+! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
+  doesn't actually do anything yet, but keep your eyes peeled.
+! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
+! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

+- Fixed buggy chameleon-support for ins and del
+. Added support for IDREF attributes (i.e. for)
+. Renamed HTMLPurifier_AttrDef_Class to HTMLPurifier_AttrDef_Nmtokens

+  is false when you're not inline and an integer of the parent that
+  caused you to become inline when you are (so possibly zero)
+. Removed ElementDef->type in favor of ElementDef->descendants_are_inline
+  and HTMLDefinition->content_sets
+. StrictBlockquote now reports what elements its supposed to allow,
+  rather than what it does allow
+. Removed HTMLDefinition->info_flow_elements in favor of
+  HTMLDefinition->content_sets['Flow']
+. Removed redundant "exclusionary" definitions from DTD roster
+. StrictBlockquote now requires a construction parameter as if it
+  were an Required ChildDef, this is the "real" set of allowed elements
+. AttrDef partitioned into HTML, CSS and URI segments
+. Modify Youtube filter regexp to be multiline
+. Require both PHP5 and DOM extension in order to use DOMLex, fixes
+  some edge cases where a DOMDocument class exists in a PHP4 environment
+  due to DOM XML extension.

+  version number string.
+- Fixed fatal error thrown by upper-cased language attributes
+- printDefinition.php: added labels, added better clarification

+! New directives %URI.DisableExternalResources and %URI.DisableResources
+! New directive %Attr.DisableURI, which eliminates all hyperlinking
+! New directive %URI.Munge, munges URI so you can use some sort of redirector
+  service to avoid PageRank leaks or warn users that they are exiting your site.
+! Added spiffy new smoketest printDefinition.php, which lets you twiddle with
+  the configuration settings and see how the internal rules are affected.
+! New directive %URI.HostBlacklist for blocking links to bad hosts.
+  xssAttacks.php smoketest updated accordingly.
+- Added missing type to ChildDef_Chameleon

+  + %Attr.IDPrefix - %Attr.IDBlacklist alternative that munges all user IDs
+    so that they don't collide with your IDs

+ *
+ * HTML Purifier is an HTML filter that will take an arbitrary snippet of
+ * HTML and rigorously test, validate and filter it into a version that
+ * is safe for output onto webpages. It achieves this by:
+ *
+ *  -# Lexing (parsing into tokens) the document,
+ *  -# Executing various strategies on the tokens:
+ *      -# Removing all elements not in the whitelist,
+ *      -# Making the tokens well-formed,
+ *      -# Fixing the nesting of the nodes, and
+ *      -# Validating attributes of the nodes; and
+ *  -# Generating HTML from the purified tokens.
+ *
+ * However, most users will only need to interface with the HTMLPurifier
+ * and HTMLPurifier_Config.

+AutoFormat.RemoveEmpty
+TYPE: bool
+VERSION: 3.2.0
+DEFAULT: false
+--DESCRIPTION--
+<p>
+  When enabled, HTML Purifier will attempt to remove empty elements that
+  contribute no semantic information to the document. The following types
+  of nodes will be removed:
+</p>
+<ul><li>
+    Tags with no attributes and no content, and that are not empty
+    elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
+    <code>&lt;br /&gt;</code>), and
+  </li>
+  <li>
+    Tags with no content, except for:<ul>
+      <li>The <code>colgroup</code> element, or</li>
+      <li>
+        Elements with the <code>id</code> or <code>name</code> attribute,
+        when those attributes are permitted on those elements.
+      </li>
+    </ul></li>
+</ul>
+<p>
+  Please be very careful when using this functionality; while it may not
+  seem that empty elements contain useful information, they can alter the
+  layout of a document given appropriate styling. This directive is most
+  useful when you are processing machine-generated HTML, please avoid using
+  it on regular user HTML.
+</p>
+<p>
+  Elements that contain only whitespace will be treated as empty. Non-breaking
+  spaces, however, do not count as whitespace.
+</p>
+<p>
+  This algorithm is not perfect; you may still notice some empty tags,
+  particularly if a node had elements, but those elements were later removed
+  because they were not permitted in that context, or tags that, after
+  being auto-closed by another tag, where empty. This is for safety reasons
+  to prevent clever code from breaking validation. The general rule of thumb:
+  if a tag looked empty on the way end, it will get removed; if HTML Purifier
+  made it empty, it will stay.

+
+<p>
+  If you would like users to be able to define external stylesheets, but
+  only allow them to specify CSS declarations for a specific node and
+  prevent them from fiddling with other elements, use this directive.
+  It accepts any valid CSS selector, and will prepend this to any
+  CSS declaration extracted from the document. For example, if this
+  directive is set to <code>#user-content</code> and a user uses the
+  selector <code>a:hover</code>, the final selector will be
+  <code>#user-content a:hover</code>.
+</p>
+<p>
+  The comma shorthand may be used; consider the above example, with
+  <code>#user-content, #user-content2</code>, the final selector will
+  be <code>#user-content a:hover, #user-content2 a:hover</code>.
+</p>
+<p>
+  <strong>Warning:</strong> It is possible for users to bypass this measure
+  using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
+  Purifier, and I am working to get it fixed. Until then, HTML Purifier
+  performs a basic check to prevent this.

+URI.Munge
+TYPE: string/null
+VERSION: 1.3.0
+DEFAULT: NULL
+--DESCRIPTION--
+
+<p>
+    Munges all browsable (usually http, https and ftp)
+    absolute URIs into another URI, usually a URI redirection service.
+    This directive accepts a URI, formatted with a <code>%s</code> where
+    the url-encoded original URI should be inserted (sample:
+    <code>http://www.google.com/url?q=%s</code>).
+</p>
+<p>
+    Uses for this directive:
+</p>
+<ul>
+    <li>
+        Prevent PageRank leaks, while being fairly transparent
+        to users (you may also want to add some client side JavaScript to
+        override the text in the statusbar). <strong>Notice</strong>:
+        Many security experts believe that this form of protection does not deter spam-bots.
+    </li>
+    <li>
+        Redirect users to a splash page telling them they are leaving your
+        website. While this is poor usability practice, it is often mandated
+        in corporate environments.
+    </li>
+</ul>
+<p>
+    Prior to HTML Purifier 3.1.1, this directive also enabled the munging
+    of browsable external resources, which could break things if your redirection
+    script was a splash page or used <code>meta</code> tags. To revert to
+    previous behavior, please use %URI.MungeResources.
+</p>
+<p>
+    You may want to also use %URI.MungeSecretKey along with this directive
+    in order to enforce what URIs your redirector script allows. Open
+    redirector scripts can be a security risk and negatively affect the
+    reputation of your domain name.
+</p>

+    and other embedded resources will break.

+    <strong>Warning:</strong> It is strongly advised you use this in conjunction
+    %URI.MungeSecretKey to mitigate the security risk of an open redirector.

+URI.MungeSecretKey
+TYPE: string/null
+VERSION: 3.1.1
+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+    This directive enables secure checksum generation along with %URI.Munge.
+    It should be set to a secure key that is not shared with anyone else.
+    The checksum can be placed in the URI using %t. Use of this checksum
+    affords an additional level of protection by allowing a redirector
+    to check if a URI has passed through HTML Purifier with this line:
+</p>
+
+<pre>$checksum === sha1($secret_key . ':' . $url)</pre>
+
+<p>
+    If the output is TRUE, the redirector script should accept the URI.
+</p>
+
+<p>
+    Please note that it would still be possible for an attacker to procure
+    secure hashes en-mass by abusing your website's Preview feature or the
+    like, but this service affords an additional level of protection
+    that should be combined with website blacklisting.
+</p>
+
+<p>
+    Remember this has no effect if %URI.Munge is not on.

+ * Forgivingly lexes HTML (SGML-style) markup into tokens.

+ * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose

+ * A lexer is HTML-oriented: it might work with XML, but it's not

+ * reasons. This might change in the future. Also, most tokenizers are not
+ * expected to handle DTDs or PIs.
+ *
+ * This class should not be directly instantiated, but you may use create() to
+ * retrieve a default copy of the lexer.  Being a supertype, this class
+ * does not actually define any implementation, but offers commonly used
+ * convenience functions for subclasses.
+ *
+ * @note The unit tests will instantiate this class for testing purposes, as
+ *       many of the utility functions require a class to be instantiated.
+ *       This means that, even though this class is not runnable, it will
+ *       not be declared abstract.

+ * @par

+ * @note
+ * We use tokens rather than create a DOM representation because DOM would:
+ *
+ * @par
+ *  -# Require more processing and memory to create,
+ *  -# Is not streamable, and
+ *  -# Has the entire document structure (html and body not needed).
+ *
+ * @par
+ * However, DOM is helpful in that it makes it easy to move around nodes
+ * without a lot of lookaheads to see when a tag is closed. This is a
+ * limitation of the token system and some workarounds would be nice.

+ * The second objective is to ensure that explicitly excluded elements of
