<p>This document was published by the <a href="http://www.w3.org/International/multilingualweb/lt/">MultilingualWeb-LT
Working Group</a> as a <del class="diff-old">Last Call Working
Draft. The Last Call period ends 10 September 2013. The publication
reflects changes made since</del> <ins class="diff-chg">Proposed
Recommendation. Comments submitted against</ins> the <a href="http://www.w3.org/TR/2013/WD-its20-20130820/">previous Last Call

<ins class="diff-chg">comment tracking document</ins></a>
.<ins class="diff-chg">All of the comments resulted in
non-normative changes to the specification. The Working Group has
completed and approved this specification's</ins> <a href="https://github.com/w3c/its-2.0-testsuite/"><ins class="diff-chg">Test Suite</ins></a> <ins class="diff-chg">and created

document to Recommendation status (see <a href="http://www.w3.org/2004/02/Process-20040205/tr.html#maturity-levels">

<del class="diff-old">All last call issues in the normative
sections (from Section 3: Notation and Terminology to Section 8:
Description of Data Categories and Appendix A: References to
Appendix D: Schemas for ITS ) have been resolved. As announced in
the previous draft , the other, non-normative sections have been
updated with explanatory material. The Working Group encourages
feedback until 10 September 2013.</del>
<p><del class="diff-old">One substantive change was made that
requires a third last call draft: the conversion to NIF was
categorized as a non-normative feature (this was a normative
feature in the previous draft ).</del> The <del class="diff-old">working group encourages especially feedback on this
change from the RDF community. Since the ITS 2.0 test suite already
has a high coverage for normative features of this specification,
the Working Group expects</del> <ins class="diff-chg">W3C
Membership and other interested parties are invited</ins> to
<del class="diff-old">advance</del> <ins class="diff-chg">review</ins> the <del class="diff-old">specification
