For each NS registered in whois / parent zone
	dig NS +norec zone +short @NS | tr '[A-Z]' '[a-z]' | sort
	if (NS set does not match)
		flag for followup where followup involved re-testing

			for zone.

This is not rocket science.  The tools have existed to do this for
decades now. 

As for whether the Registry / Registrar performs the actual looks
I don't care.  The Registry is clearly responsible for ensuring
that they get performed as they are responsible for the overall
operations of the parent zone.
