Not entirely — or at least so the Schema adherents would argue — but more
importantly, for most relevant published standards the only normative
conformance criteria are a DTD or set of DTDs. W3C Recommendations whose
normative definition is provided in the form of a Schema of some sort are only
just beginning to appear.

This is a different issue. The term “validation” has a specific and established
meaning in the SGML (and XML) context. Using this term to descibe a different
process is confusing and imprecise.

For a tool whose ambition it is to check overall conformance — a superset of
what validation provides — it would be more appropriate to label it as a
“conformance checker” (note “checker” rather then “validator”); particularly
when the tool doesn't perform validation per se at all!

“Violence accomplishes nothing.”   What a contemptible lie!    Raw, naked
 violence  has  settled  more  issues  throughout  history than any other
 method ever employed.  Perhaps the city fathers of Carthage could debate
 the issue, with Hitler and Alexander as judges?
