[microformats-discuss] Discovery of microformats

I for one would like to reinforce that the profile mechanism is a  
good one and should be used more often.

Let me also take this opportunity to point out that the profile  
mechanism could be improved.  It requires that you use a profile  
attribute in the head element.  If you are creating a web page of  
harvested microformatted content or one where microformatted content  
is inserted by something like hCard creator, you typically do not  
have access to the head element.  What to do?  Perhaps we need to  
consider a use of the anchor <a> or some other element, i.e.,

<a href="profile.url" rel="profile">profile for microformat z</a>

contained in the inserted text.

I'm a little concerned with relying on UA parsing as the sole  
fallback.  It requires that the UA have an updated notion of what the  
microformats are.  How would that happen?  The profile mechanism  
seems easier.
