	I do wish people would get terminology right.  DNS is hard enough
	for the novice without using terms incorrectly.

	It's the name of a "zone".  It also happens to be a domain
	name but in this case the constraint is because it the name
	of the zone, i.e. it has SOA and NS RRsets (resource record
	sets).

	From the FAQ.

Q: I get error messages like "multiple RRs of singleton type" and
   "CNAME and other data" when transferring a zone. What does this
   mean?

A: These indicate a malformed master zone. You can identify the
   exact records involved by transferring the zone using dig then
   running named-checkzone on it.
   
   dig axfr example.com @master-server > tmp
   named-checkzone example.com tmp

   A CNAME record cannot exist with the same name as another record except
   for the DNSSEC records which prove its existance (NSEC).

   RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node,
   no other data should be present; this ensures that the data for
   a canonical name and its aliases cannot be different. This rule
   also insures that a cached CNAME can be used without checking
   with an authoritative server for other RR types."
