<h2><a name="abstract" id="abstract"></a> Abstract</h2>
<p>This document defines data categories and their implementation as a set of
elements and attributes called the <em>Internationalization Tag Set (ITS)</em> 2.0.
ITS 2.0 is the successor of <a href="http://www.w3.org/TR/2007/REC-its-20070403/">ITS
1.0</a> ; it is designed to foster the creation of multilingual Web content, focusing
on <del class="diff-old">HTML5,</del> <ins class="diff-chg">HTML,</ins> XML based
formats in general, and to leverage localization workflows based on the XML
Localization Interchange File Format (XLIFF). <del class="diff-old">In addition to
using ITS 2.0 for HTML5 and XML content, an algorithm to convert that content to NIF
is provided.</del></p>
