	Data is accepted if you can prove you have control of the
	nameservers for the zone.  We also pull in the ITAR contents.

	No it doesn't.  When IANA signs the root and you add the
	trusted keys for the root to named.conf named won't look
	in the DLV to validate answers that are part of the island
	of security identified by the root's trusted key.

	This applies for all trusted-keys.  Named only looks in the
	DLV if the answer is insecure using the configured trusted

	We would love to have the root and org signed as then it
	wouldn't be necessary to have a trusted key for dlv.isc.org
	unless you wanted one.

	DLV bridges the gaps in the DNSSEC trust paths.  It doesn't
	replace the DNSSEC trust paths.  At the moment there is a
	gap at the root.
