I suspect dig actually asked the real root servers in the Internet.
Make sure that it directly asks your own (internal?) root server which
manages the imaginary "ipv6.domain".

NXDOMAIN is a BIND specific terminology which represents RCODE 3 and
stands for non existent domain.  Since an RFC should be "neutral", it
uses the standard keyword.

BTW: RFC4074 is not a very appropriate reference in this context.  You
might rather want to refer to more basic reference to DNS, such as
RFC1034 and/or RFC1035.
