I was thinking along similar lines.  I've been adding something like this
to my XML documents:

	<prop name="state" xml:regexp="[A-Z]+">NY</prop>

So the parser can verify that the CDATA matches the regular expression.
Works OK for content, but I don't see how I can add this meta-meta-data for
attributes.  That is to say, how can I tell the parser that the 'name'
attribute value for the 'prop' entity must be of the form
"[a-zA-Z_][0-9a-zA-Z_]*"?

Of course this also brings up the murky waters of grep syntax, which I've
been avoiding.
