	The draft documents a existing service (that's one reason
	why it will get the Experimental tag).  The service is not
	going to change.  The document has passed dnsops review on
	that basis.

	If there was a clean slate implementation then DNAME rather
	than NS records would be used as they require far less work
	to be done for each address change.  6to4 space is highly
	dynamic and setting up new zones after each address change
	is a pain. That pain goes away when DNAME is used.
