That sounds reasonable, but...

Not always - the following is valid (though rather unusual!) RDF/XML :

<html xmlns="http://www.w3.org/1999/xhtml">

Yep. Hmm, if there was a neat way to provide the media (mime) type it
could also be useful for non-XML docs as well. Otherwise an easy
workaround for RDF might be to specify that the root element for RDF
docs must be <rdf:RDF
xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#" /> (as was the
case in the pre-2004 RDF specs).
