Henri,
I would like to have one point of clarification, if I may...

Your approach is to phase out CURIE-s altogether on technical grounds.
However, isn't it correct that those issues disappear if the current
@xmlns:ABCD mechanism is exchanged against a @prefix="ABCD=blabla"
approach? Although details of this alternative are not yet fixed, it is
under discussion in the group and many RDFa tools (including my
distiller) already implements a variant of this.
Thanks
