... NXDOMAIN at a empty non terminal only came about as the result of bad wording in RFC 2535. "no names" should have been "no names with data" (the difference is crucial in determining which rcode is returned). Only RFC 2535 nameservers are allowed to return NXDOMAIN for a empty non-terminal and they should few and far between these days. Every other NXDOMAIN at a empty non terminal is the result of miss-interpreting STD 13 or a operational error e.g. missing delegation in a parent zone.
i'd still like to see a standards track clarification. djb wrote a name server which responds with nxdomain for empty nonterminals, and upon re-reading the scriptures, i found that his interpretation wasn't completely unreasonable.
