Interestingly, there were a bunch of similar errors with virtuosos, too...

What I meant was that the RDF/XML (which came from pyRdfa, I suppose) 
was wrong. My mistake. However, I handled the issue since then (it was a 
bug in the XML serializer of RDFLib, actually, so the turtle/n3 was 
always correct), so the output of pyRdfa should be o.k. now.

Thanks Manu
