* eTemplate2 XML schema

* 1. we read the legacy etemplate2.dtd converted by PHPStorm (Tools > XML Actions > Convert Schema) to Relax NG with an XML parser
|

* 2. remove the obsolete widgets
|

* 3. add new widgets from custom-elements.json file generated by our documentation build
|

* 3. add new widgets from components.json file generated by our documentation build (and enhanced with attributes inherited from Shoelace )
|
||||
* 4. apply overwrites below
|
||||
* 5. output it again as new eTemplate2 Relax NG schema
|
||||
* 6. convert it again via PHPStorm (Tools > XML Actions > Convert Schema) to etemplate2.0.dtd referenced in our xet files
|
||||
* (until we figure out how to use RELAX NG direct)
|

|
||||
* Open problems:
|
||||
* - custom-elements.json has no information about element hierarchy: not all elements are allowed be contained by an arbitrary element
|
||||
* - components.json has no information about element hierarchy: not all elements are allowed be contained by an arbitrary element
|
||||
* - Relax NG can define attribute types, need to check how with match our internal types to the xet attributes
