   4   * XHTML 1.1 Legacy module defines elements that were previously
   5   * deprecated.
   6   *
   7   * @note Not all legacy elements have been implemented yet, which
   8   *       is a bit of a reverse problem as compared to browsers! In
   9   *       addition, this legacy module may implement a bit more than
  10   *       mandated by XHTML 1.1.
  11   *
  12   * This module can be used in combination with TransformToStrict in order
  13   * to transform as many deprecated elements as possible, but retain
  14   * questionably deprecated elements that do not have good alternatives
  15   * as well as transform elements that don't have an implementation.
  16   * See docs/ref-strictness.txt for more details.
