In the second case I think the NS records should be there in the Authority Section. Consider this case: example.com. IN NS dns.example.com. l2.example.com. IN NS dns.example.com. l3.l2.example.com. IN NS dns.example.com. When a query for example, dig l3.l2.example.com @dns.example.com, the nameserver answser without the Authority Section, then the client won't know the answer is in which authority zone.
