These questions would be better forwarded to the microformats.org mailing 
lists. The WHATWG spec won't make the <card> and <calendar> elements use 
hCard and hCalendar until/unless the relevant specs are much clearer about 
the points you raise.

The <card> and <calendar> sections in the WA1 spec right now are nothing 
but placeholders (hence the "TBW" marker on the section headers).
