(Originally sent to the WHAT WG list. I was advised to resend here.)

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.)

I am developing a conformance checker for HTML5, and HTML5 may end up  
making a normative reference to hCalendar and hCard.
