Ok, let me phrase this another way:

Why is conformance-to-a-subset-of-the-conformance-requirements-that-
happens-to-be-describable-using-a-particular-schema-language a concept
that needs its own term?

It seems to me that by making such a fuss over conformance to that subset
you are diluting the point of conformance to the whole specification.

The funniest thing is that using your definition, the following:


...is invalid in HTML4, but valid in XHTML1, even though the _only_ reason
for this difference is a limitation of the schema language used for XHTML.
(XML DTDs don't support inclusions and exclusions).
