Well, auto-discovery is only one way to discover, I shouldn't have  
used that as the subject. I wanted to know about discovery by either  
me *or* a UA.

A particular use-case would be like what I do with RSS in Safari or  
Firefox...I browse to a web site and I get notification that there is  
another format in play...

(The resulting discussion was exactly what I was looking for)
