Hi Tony,

We try to solve similar wildcard problem.

NSEC/NSEC3 aggressiveuse (Section 5.3 Wildcards
<https://tools.ietf.org/html/draft-ietf-dnsop-nsec-aggressiveuse-10#page-6>)
:
- NSEC/NSEC3 RR: give "NOT EXIST SUBDOMAIN" information.
- cached deduced wildcard: give the default wildcard RR.

SWILD:
- Directly give "ALL SUBDOMAIN" information, and the default wildcard RR.

SWILD is applicable even when Authoritative Nameservers don't give
NSEC/NSEC3 RR.
SWILD is applicable on non-validating Forwarding Resolvers.

Regards,
