Thanks, please do commit them (I can't) ; I changed the online version here:

Well no... this really is due to a lack of time: there is a stable 
section explaining this aspect of the syntax in the specs but to 
implement it properly I need to rewrite some of the core templates of 
the transformation to be able to switch from "rdf:about" or 
"rdf:resource" to "rdf:nodeID" when I generate triples attached to blank 
nodes. The current transforms gives generated rdf:IDs to blank nodes and 
this is a bad hack I should remove as soon as I have the time to do it ; 
then I will be able to address blank node CURIES properly.

Yes and as of today there is nothing about this in the RDFa syntax specs 
that's while I removed the templates I had for it.
