/**
|
|
* XHTML 1.1 Legacy module defines elements that were previously
|
|
* deprecated.
|
|
*
|
|
* @note Not all legacy elements have been implemented yet, which
|
|
* is a bit of a reverse problem as compared to browsers! In
|
|
* addition, this legacy module may implement a bit more than
|
|
* mandated by XHTML 1.1.
|
|
*
|
|
* This module can be used in combination with TransformToStrict in order
|
|
* to transform as many deprecated elements as possible, but retain
|
|
* questionably deprecated elements that do not have good alternatives
|
|
* as well as transform elements that don't have an implementation.
|
|
* See docs/ref-strictness.txt for more details.
