For anyone interested, the discussion yesterday on XHTML prompted me to
finish a counter-proposal to the XML Schema draft.
My proposal "XML Notation Schemas" is at
http://www.ascc.net/~ricko/notation.htm
The relevance of the proposal to this group is that, by concentrating on
notations and not on content models or namespace names, a MIME media-type
signature like the one I gave yesterday could be automatcally extracted from
the schema.
This might help some of the XHTML issues.
