I'm hoping Henry will be able to write this.

Actually, I think Mike is referring to the type attribute,
not the media attribute here.

In fact, during our earlier discussion, we decided that we
would NOT disallow type="text/xsl", so our current text that
says that the type attribute MUST match RFC 2616 needs to be
changed.  Maybe just change MUST to SHOULD.

I continue to hesitate to have this spec say much about the
values of the PAs, but I could live with an informative note
about text/xsl.

If this is true, we can have an informative note.  I wouldn't
be surprised if this were true, but I also wouldn't be
surprised if this issue were more complicated.  I'm hoping
someone on the WG can weigh in here (John?).

We can add a note and a non-normative reference.  The relevant
section is http://www.w3.org/TR/xslt20/#embedded
