To my knowledge there seems to be three technical issues now.

1. There should be additional pseudo-attribute for identifying schema
language used (for schemas that has media type application/xml).
see http://lists.w3.org/Archives/Public/public-xml-core-wg/2010Jan/0050.html

- open questions:
  - how to name such pseudo-attribute
  - should it hold just namespace URI or list of namespace URIs (to
handle situations like RELAX NG schema with embedded schematron)

2. Additional pseudo-attributes should be allowed because in future we
can add new schema-specific pseudo-attributes like phase
see comments fro MSMQ or
http://lists.w3.org/Archives/Public/xml-editor/2010JanMar/0000.html

3. Handling of conflicting media types
see http://lists.w3.org/Archives/Public/xml-editor/2010JanMar/0001.html
Personally, I don't have strong position on this. I have always though
that type is useful only when you fetch resource from local filesystem
where HTTP is not involved and media type can't be delivered via
Content-type HTTP header.
