I think it boils down to one question: do you want to define your own
datatype with ID semantics?
If no, then there is no problem. RELAX NG lets you define whatever
datatype library as long as (1) it returns simple yes/no and (2) it has
no other sideeffect whatsoever.
If yes, then I understand that you think it is a problem. But
considering our position that this ID functionality is just for
compatibility only, I guess we should wait for the more comprehensive
spec that covers the cross-reference problem.
