To put it bluntly, is it really clear that using XML Schema as an 'integral
part' of any other spec is a good idea at this point?
Or would it make more sense for XForms to take an approach like the that of
the DOM Level 3 Content Model material, which can work with multiple schema
types? (Yes, I know they're very different projects, but some days...)
Historically, it looks like XML Schema got piled on at a late date:

Interesting language, that.
