	The part of RFC 1034 I quoted puts the responsability on
	*both* parties in the delegation.

	I'm pushing the registries at this stage because they, on
	the whole, have been neglecting their responsabilities.
	There are other nameservers than BIND that are excessively
	permissive or just plain out break compliance.

	Child zone operaters will ignore problem reported to them
	(particularly in logs) until a zone fails to load or a
	delegation is pulled.
