[whatwg] Conformance criteria for hCard and hCalendar

How is one supposed to extract conformance requirements from the  
hCard and hCalendar specs? The section that defines the format in  
both specs is rather short. Is it an obvious bijective mapping  
between hCalendar/iCalendar and hCard/vCard for those who are  
familiar with the iCalendar and vCard formats? (It isn't obvious to  
me.) The existence of
suggests that the specs themselves are not sufficient descriptions of  
the formats and their processing.

Are there even any conformance requirements for these formats? (The  
specs seem to encourage view source instead of pointing to  
conformance criteria.)

Also, an example in the Web Apps 1.0 spec suggests that the <card>  
element does not replace the class='vcard' root of the card. It would  
be nice to be explicit about this in the prose. (Why is the content  
model then any block level elements instead of exactly one block  
level element or zero or one block level elements?)
