Hello Scott I don't understand your issue , are you suggesting that a 
hcard may have more than one UID element?

The UID element *is* the Unique Identifier of an entire hcard/vcard

Correct, what If I had multiple hcards on a single page for different 
organizations or companies I work for all marked containing uid, every 
@href attribute may be different but all essentially Me, In my address 
book I have multiple contacts for the same person, Don't you?

Anyway you missed my point what I was saying is that no two uid values 
on a page should be the same even if they are for different people, make 
them different somehow.

what I  said about authoritative hcard, I ment representative hcard 
sorry my mistake
