Also, with well-formedness it is possible to use an SGML DTD and XML
documents.  I suspect this will be a well exercised option for the
"heavy hitters."  Perhaps we should consider the DTD model of XML 1.0
as DTDs with training wheels and come back with a more complex version
which supports parameter entities and "&" in content models (which
seem to be the two biggest holes, if the former is dropped), etc.  It
is true that this would be much more work than the MGSW, but (if you
know you're pumping out well-formed XML) still much less than SP.  In
any case, if XML DTD's are too clumsy, people will go back to SGML for
validation.  XML 1.0 might even have a short appendix on how to write
a DTD to produce valid XML.
