Actually it is perfectly okay (i.e. conformant) for a non-validating parser
to disregard external entities, including the external DTD subset. Evidence
the xml 1.0 recommendation, 5.1 [1] reads: "Non-validating processors are
required to check only the document entity, including the entire internal
DTD subset, for well-formedness."
But it is usually much more friendly for even a non-validating processor to
read all entities.
