/**

* 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.
