I am afraid its not as simple as it might be. What you have to do is
locate a Relax NG grammar for XHTML (let's call it xhtml.rng) and then
massage TEI patterns by hand. Thus:

      <moduleRef url="">
	  <rng:define name="model.inter" combine="choice">
	    <rng:ref name="html.table"/>

 a) <moduleRef>'s @url loads an external file of Relax NG code
 b) <moduleRef> has an optional <content> child whose contents are
    injected into the final schema.
 c) you have to add to one of the TEI class patterns. we modify class.inter.

What's wrong with this? Something serious - the pattern which identifies
the HTML table element in xhtml.rng is actually "table", which is
identical to the name in TEI. So in the example above I have used
"html.table", which would mean changing the XHTML RNG file. Names of
things in Relax NG are NOT name-spaced, unfortunately.

If this isn't making sense, please shout!
