  Including at the RNG level should work well for this :-)

  okay, tell me if you can, it might be easier than including the full
XHTML relax ng schemas which span a number of files and multiple directories.

  Should be quite easy, especially if using the W3C XML Schemas datatypes.

  Well Relax-NG has less traction at the moment. For structured edititing
support it's a bit harder because RNG is indeterministic. So providing
suggestions to the user is not as simple as looking at the label out from
the current state in a deterministic automata. A good job might be harder,
for example depending on the type of an attribute you could generate different
child element to the current node (not that I suggest doing this kind of
things, but RNG is inherently more powerful and also more complex to handle 
correctly for this kind of work).
