+Subject: Unload a zone if a transfer breaks its SOA record
+
+If a zone transfer results in a zone not having any NS records, named
+stops serving it because such a zone is broken.  Do the same if an
+incoming zone transfer results in a zone lacking an SOA record at the
+apex or containing more than one SOA record.
