I don't think NS records are required, but I'd have thought an SOA
record would be. RFC 1035, section 5.2 says "should" but not "must":
"Exactly one SOA RR should be present at the top of the zone."
BIND's named-checkzone issues the following diagnostics when I checkzone
a file containing a single A record:
zone foo.bar/IN: has 0 SOA records
zone foo.bar/IN: has no NS records
Hope that helps a bit.
