No and Yes. No in that an argument could be made that the old parsing
routine fell under the "be liberal in what you accept" rules. Yes in that
the Master File Format is intended to provide an interchangable database
table, so while BIND may have been liberal it was doing so at the expense
of some interoperability measures.

The real culprit in this story is the script-generator. It should have
been cranking out standard-compliant zone files from day one.
