In the case of Schemas, I'd certainly hope this isn't a real problem. Various W3C folks have participated on ietf-xml-mime, and they do seem to be aware both of the existence of the registration process and the latest drafts. For RELAX, I suspect Murata Makoto will be ready with a registration. He is, after, the lead author on the IETF drafts describing XML MIME type registration. For Schematron, it starts getting trickier, since its foundation is XSLT. It has more options, basically. >A major advantage of >namespaces is that they are available to anyone who can create a URI.

I'm not sure what you're referencing in the last paragraph - maybe it's just that I haven't seen any of these options widely deployed, though possibilities exist for all of them.
