But it's not DTDs that are well-formed or valid. It's documents. Nowhere in
the XML specification is validity or well-formedness of a DTD, separate
from a document, defined. And it's certainly true that whatever the DTD,
you can attach documents to it that are non-well-formed and/or invalid (and
which a parser will report is such). In other words, you can't validate a
DTD alone, so there's no point in worrying about what happens if you try.
