[uf-discuss] Enumerating Microformats on a Page

[Breton Slivka]

I've only just recently figured out what xmdp's are, and what they're  
capable of.  I notice the structure of your hcard/hreview/hcalendar  
thing is such that you can pick an attribute, and search for bits of  
data which contain that attribute.   Have you attempted to detect and  
parse XMDP's not for validation, but to discover new microformats not  
documented at microformats.org?   Now don't get me wrong, I  
understand the importance of strong standardization, but say someone  
creates a niche format for their own site, and related sites in their  
community with an xmdp,   do you think your aggregator could use that  
xmdp to create new searchable attributes in your search engine?

Sorry this is a bit of a tangent, but the idea of it kind of  
fascinated me.
