- Be lenient when a NSEC NameError response with RCODE=NXDOMAIN is   received. This is okay according 4035, but not after revising   existence in 4592.  NSEC empty non-terminals exist and thus the   RCODE should have been NOERROR. If this occurs, and the RRsets   are secure, we set the RCODE to NOERROR and the security status   of the reponse is also considered secure.
