Well, we should expect more:
* All NS records in the zone must point at authoritative servers.
* If glue is needed in the delegation, that record must be present in the
zone. And all addresses of that glue must point at authoritative servers.
* The SOA record must have a working email address.
* All non-glue NS records must point at names having an A record in its
authoritative zone.
* All servers must have identical SOA and NS RR set.
