True, but the XML spec says that validating parsers must report
violations of validity constraints, and a document without a DTD
will violate at least one.

Yes, the Infoset doesn't address validity except in the cases where
invalidity prevents an item from having a value (notably the
[references] property of attributes).

All that's required is there must be such a mechanism for a validating
parser.
