+; There are several zones hosted on one server. The DS lookup needs to

+; record where the child-data does not precisely match the parent referral.
+; Even though that parent referral is not visible due to the zones that are
+; on one server. The DS lookup fetches the child-side NS record.
+; And then should lookup the DS with it.
+;
+; In foo2.test there is an actual referral, the server host the upper and

+; child side data when queried for the middle NS record.
+;
+; In foo3.test the zone is co-hosted, also the middle zone, and the glue
+; is correct, there is no mismatch with the NS record. It points to the

+; that is from the wrong zone if that server supported DNSSEC for qtype DS.
+;
+; In foo4.test the zone is co-hosted and the server supports DNSSEC for
