This does not satisfy me, at the very least this clarification needs to
be added to the draft, but that would not make much sense. If the prose
considers a specific document compliant while the schema does not, that
is a conflict between prose and schema. It seems what you are trying to
say is that only documents that comply to the prose *and* schema comply
to the specification. That's redundant with appendix D.3.1 so I arrive
at my original conclusion that either all conflicts or the statement
under discussion should be removed.
