/**

 * 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.
