Right...because no-one is proposing the others in this document.

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

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.
