I'm glad Xiaoming expressed the case for URI so well. I just added it  
to the uid-brainstorming [1] page. I have to admit I've seen the need  
for a  identifying URIs elsewhere and when Tantek pinged microformats- 
discuss with a straw proposal [2] that would help the LiveClipboard  
and upcoming.org folks I saw an opening to sneak in functionality for  
marking up URIs more generally.

The naming 'uri' vs 'uid' aside, would it be reasonable to RECOMMEND  
that a URI is used (thus including URLs) and leaving the door open to  
less useful ids should people want to use them? This would allow the  
current hCard behavior to be preserved:

	"UID in vCard simply becomes another semantic applied to a specific  
URL (or EMAIL) for an hCard."

As Xiaoming suggests both 'http' and 'mailto' are valid URI schemes  
in RFC4395. Allowing a UID this flexibility would mean a UID could  
serve as a module that hCard and hCalendar (and perhaps an hCite and  
others) reference.
