Seems to me that it belongs in the answer section, since for aname-aware
reasolvers the aname is the answer.

Type bitmaps like the ones in NSEC wouldn't be hard to implement.  Add
some sanity rules saying that type bits for DNSSEC types and the like
are ignored, and it's an error to include any types also present at
the same name.
