The Authority and Additional sections are only filled in for data
referenced in the Answer section.  When you query for the SOA record of a
subdomain, there isn't anything in the Answer section.

There's something wrong with these clients, then.  Putting data in the
Authority and Additional sections is merely a convenience, it's not
required.  It saves the client from having to do a separate query for that
data, but if it's not there they can always do so.
