Well, that depends on whether the schema processor have DTD validation
turned on or not. If YES then all entities should be resolved BUT in this
case you also need to specify the complete XML document as a DTD grammar
otherwise it won't pass DTD validation. Note that this could just be a
very loose DTD syntax using ANY for all elements but it's still a bit
tedious. If the schema validator doesn't have DTD validation turned on
it's up to the processor to resolve external entities which means that
some processors will resolve them and some won't. Last time I tested this
XML Spy did resolve them while MSXML4 didn't so there could be problems
using this approach.
I've had a discussion with Henry about this but I can't seem to find the
email in the archives.

Cheers,
