[uf-discuss] hAtom draft - class="title"

Hi Paul,

hAtom:content, hAtom:author and hAtom:contributor are all opaque [1], 
that is, hAtom parsers must stop searching for hAtom content within 
these elements.

Thus, you can safely nest a hCard side any of these elements without 
worry of conflicts. There has been an issue raised [2] about hCards 
appearing in other places. I'm not sure if it's a critical issue on 
80-20 principles.

Regards, etc...
