   RE: [xml-dev] XQuery and DTD/Schema?

[ Lists Home | Date Index | Thread Index ]

Good question. I have another. My apologies if it has already been clearly
answered but I don't think it has.

I am looking for a technical, non-political reason why RELAX NG has been
brushed aside by XQuery.

Any XQuery people want to speak to that?
