I have idea of creating system table for holding DTDs, XSDs, Relax-NGs (similar
as on ORACLE).
Is that good idea?
I doubt it. Why would we want to do that?
If I understand, it allows a local copy of DTD, .. so then is possible
to provide a fast DTD checking.
But that could equally well be stored in a user table rather than a
system table.
Yeah. The trouble is you won't be able to use that reliably in a check
constraint, which I imagine is one of the principal intended purposes.
I'm not sure how we should go about that.
