This is a great start; as I revise the XSchema sections I'll try to make sure
these terms are used _consistently_.

Here I disagree. I don't want to conflate validation against a DTD with
checking (verification? still fishing for a good word) against an XSchema.
The process is similar, but not identical.
I also need terms to describe the piece of software that checks a document
against an XSchema. So far I've been fumbling with XSchema processor;
Verifier or something else might be better.

I'd like to think so; at least in part that's why there's that crazy XSC:More
element for application designers to experiment with.
