Subject: [PATCH 13/57] 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.
