   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.
