-Subject: [PATCH 13/32] Treat DS and DNSKEY queries being forwarded the same as
- those locally originated.
-
-The queries will not be forwarded to a server for a domain, unless
-there's a trust anchor provided for that domain. This allows, especially,
-suitable proof of non-existance for DS records to come from
-the parent domain for domains which are not signed.
