Cool, that's what I understood. That's all good.

I presume that text would slot into draft-ietf-provreg-epp-domain-06 
section 1.1 in some way (the corresponding section in 
draft-ietf-provreg-epp-host-06 could maybe stay as-is, since if you 
need the spec for host objects you're probably not running a server 
that uses host attributes on domain objects).

The domain mapping document should presumably inherit some text along 
the lines of section 2.5 in the host mapping document, to the effect 
that "When a host object is provisioned for use as a DNS name server, 
IP addresses SHOULD be required only as needed to generate DNS glue 
records."

Stronger text which says that IP addresses MUST only be present in host 
attributes if the host name is subordinate to the containing domain 
object name sounds like it is more than is required (and e.g. will not 
be compatible with the data in the NL registry, as per Jaap.
