   4   * XHTML 1.1 Text Module, defines basic text containers. Core Module.
   5   * @note In the normative XML Schema specification, this module
   6   *       is further abstracted into the following modules:
   7   *          - Block Phrasal (address, blockquote, pre, h1, h2, h3, h4, h5, h6)
   8   *          - Block Structural (div, p)
   9   *          - Inline Phrasal (abbr, acronym, cite, code, dfn, em, kbd, q, samp, strong, var)
  10   *          - Inline Structural (br, span)
  11   *       This module, functionally, does not distinguish between these
  12   *       sub-modules, but the code is internally structured to reflect
  13   *       these distinctions.
