rfc6761 compliance

[A. Schulze]

Hello,

the RFC 6761 give some advise how caching DNS servers SHOULD
handle queries for reserved domains. Mostly it say
"do not send queries to the root name servers"

... point 4 in any case ...
http://tools.ietf.org/html/rfc6761#section-6.2 ( domain "test." )
http://tools.ietf.org/html/rfc6761#section-6.4 ( domain "invalid." )

looks like unbound don't follow that "SHOULD" recommendations.
it this a miss-configuration on my side ?

my unbound.conf:
     server:
          ip-address: ::1
          chroot: /chroot/unbound
          do-daemonize: no
          val-log-level: 2
          trust-anchor: ". DS 19036 8 2  
49AAC11D7B6F6446702E54A1607371607A1A41855200FD2CE1CDDE32F24E8FB5"
          # other options


adding local-zone statements make unbound fixes the "un-conformance" here.

     server:
         local-zone: "test." static
         local-zone: "invalid." static
