 /**
  * 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.
