Linking Category and Category Yearly templates

 <ul>
   <mt:ArchiveList archive_type="Category-Yearly">
   <li><a href="<mt:ArchiveLink>"><mt:ArchiveTitle></a></li>
   </mt:archivelist>
 </ul>

Place this in a Category archive template to generate links to Category-Yearly archives. It will output something like this:

 <ul>
   <li><a href="http://example.com/my-category/2007/">2007</a></li>
   <li><a href="http://example.com/my-category/2006/">2006</a></li>
   <li><a href="http://example.com/my-category/2005/">2005</a></li>
 </ul>
