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