Why are they different, by the way? I really do not understand
that. The "locally served zones" registry should be a strict subset of
the "special use domains" registry, for the case where RFC 6761 says
"4. Caching DNS Servers: Are developers of caching domain name servers
expected to make their implementations recognize these names as
special and treat them differently?  If so, how?" and the answer is
"serve locally".

[Speaking of this, the lack of a formal language in the "special use
domains" registry, allowing a resolver to be compiled with automatic
inclusion of all the special cases, is the only really serious problem
in RFC 6761. I regret that draft-ietf-dnsop-sutld-ps-02 does not even
mention it.]

Let me advertise again my draft :-) draft-bortzmeyer-dname-root
