/**
|
|
* 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.
