<h2><a name="abstract" id="abstract"></a> Abstract</h2>
<p>The technology described in this document - the <em>Internationalization Tag Set
(ITS) 2.0</em> - enhances the foundation to integrate automated processing of human
language into core Web technologies. ITS 2.0 bears many commonalities with is
predecessor, <a href="http://www.w3.org/TR/2007/REC-its-20070403/">ITS 1.0</a> but
provides additional concepts that are designed to foster the automated creation and
processing of multilingual Web content. ITS 2.0 focuses on HTML, XML-based formats in
general, and can leverage processing based on the XML Localization Interchange File
Format (XLIFF), as well as the Natural Language Processing Interchange Format
(NIF).</p>
