/**
 * 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.
