It's several weeks since I see the W3C pyRDFa parser spitting out RDF from my RDFa and minting the dc11 namespace abbreviation in the process. But maybe I'm interpreting signs in a too optimistic way :-) Yeah, my implementation recognizes that one alrady. But it is not really really kosher yet:-) Ivan > > Antoine > > > >> Good point.

If we accept this change, when should we do this? We are bound by a promise not to make changes often. I would therefore propose to make this change when html5+rdfa goes to CR. Tom, this would be sometimes January-February time range.
