I was trying to explain why RDFa cannot be regarded as being "layered" on top of XML namespaces, because it doesn't actually require XML namespaces. RDFa only requires a prefix mapping mechanism, and this could just as easily have been @xmlns-dc, @banana:dc, @samruby="dc=..." or something else entirely. It just so happens that the W3C already used the xmlns-based attribute naming mechanism to create tokens, so we went with that. But that is the beginning and end of RDFa's relationship with XML namespaces. I don't know what else to do to explain this really simple point.
