Wasn't my idea - the version attribute is already in XHTML+RDFa 1.0  
(and setting it is a "SHOULD" in the conformance requirements). I've  
stuck to much the same requirements, just changing the DTD and the  
value for the version attribute.

As far as implementations that use it, my own semantic web tool  
Swignition has a "strict mode" where it refuses to parse a document  
as RDFa without the version requirement. So there's at least one  
implementation that does use it.
