Thanks much!

Check my comprehension:

So, **delegation** NS records are only needed in the zone which has an $ORIGIN,
which is 1 level up from the $ORIGIN in the zone that contains the nameserver SOA, and
authority NS records in.  If this zone with delegation NS records is a subdomain
of a TLD, then one adds these delegation NS records by using the registrar's
interface to the TLD registry.
