Now license link looks like this: <li id="copyright">Projects's content is available under the <a href="http://www.gnu.org/copyleft/fdl.html" class="external " title="http://www.gnu.org/copyleft/fdl.html" rel="nofollow">GNU Free Documentation License</a>. <br /></li> I think it's will be better if we replace rel="nofollow" with rel="license nofollow". For more information you may look http://microformats.org/wiki/rel-license
I found problem. Usage with <link rel="copyright" href="..." /> not standardize now.
