I'm thinking that by "cross-validate" he means to use an inline DTD or
schema that is an integral part of the instance document.  That is one
thing that DTDs do (or rather the internal subset allows)  that XSD 
cannot do well or in a standard way.   The Microsoft XML tools support
this, but there are conceptual issues as well as interoperability
problems.  See the thread starting at

for more information.
