I do not have a problem with this; your point (in another mail) on the 
extra microformat values is well taken...

The only additional point here is: the


might be a living document; ie, the XHTML working group (or anybody else 
'owning' this document) might add legal @rel values in future even when 
RDFa is already a Rec. Ie, either an RDFa implementation would have to 
be regularly updated if there are changes, or there should be some 
mechanism whereby the allowed attribute values are automatically 
retrieved. But we can cross the bridge when we get there, this should 
not affect the rdfa-syntax document.

Thanks Manu...
