	Not quite.  The answer contained a CNAME for which there was not
	a record with that owner name in *this* answer.  This could be
	due to any of three conditions.

	1. The server didn't have the record the cname was pointing to
	   and this was a non-recursive query.
	2. The name was valid but there were no records of this type.
	3. The name does not exist.
