Looking back through the the archive I see sent this to the TAG list instead of the
 the HTML working group list. My apologies.
I had wondered why nothing else had happened in response.

This is a serious bug and one which apparently remains in http://dev.w3.org/html5/md-LC/

It is constructed including two other URIS, so that there is a combination of two authorities, so it will only be supported if the w3.org and mictorformats.org sites coordinate the generation of new microformats.   It makes W3C responsible for supporting things added in microformats.org which, while W3c may need to do this special cases should not be built into the semantics of the HTML language.
