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