// Briefly, a zone which has been declared delegation-only will be effectively
// limited to containing NS RRs for subdomains, but no actual data beyond its
// own apex (for example, its SOA RR and apex NS RRset). This can be used to
// filter out "wildcard" or "synthesized" data from NAT boxes or from
// authoritative name servers whose undelegated (in-zone) data is of no
// interest.
