Any DNS record line in a zone file can be prefixed with "DELAY=" and
a number of milliseconds (followed by one space).
-Any DNS record line in a zone file can be prefixed with "DNSSEC ";
+Any DNS record line can be prefixed with "DNSSEC ";
if all the records found by a lookup are marked
as such then the response will have the "AD" bit set.
-Any DNS record line in a zone file can be prefixed with "AA "
+Any DNS record line can be prefixed with "NXDOMAIN ";
+The record will be ignored (but the prefix set still applied);
+This lets us return a DNSSEC NXDOMAIN.

+Any DNS record line can be prefixed with "AA "
if all the records found by a lookup are marked
as such then the response will have the "AA" bit set.
