Not should, MUST be authoritative. It MUST return responses
with "aa" set in the flags to non-reqursive queries for
names within the delegated namespace or it MUST return a
referral to nameservers which in turn are authoritative for
the sub-delegated namespace.
Note: queries for the SOA record at the delegation MUST return
the SOA record with "aa" set. There is no horizontal delegation
in the DNS.

It won't work.
