I think the place to start with this - separate from the RDF and DTD
discussions - is
Should we allow internal XSchemas?
External XSchemas in some form I think are pretty much mandatory. If we
decide that we need internal XSchemas, then we need to decide how to demarcate
them as schemas _and_ how they interact with external XSchemas.
At this point, I'd say no to internal XSchemas, if only because sorting out
those details will take a long time and considerable debate. It would also
require us to find some way of hiding the internal XSchemas from non-XSchema
aware processors, something I'm not fond of.
I'll reply to the first issue, mixing DTD subsets and XSchemas, in a separate
reply regarding Question 4.
