<domain:info> command and <host>

[Robert Burbidge <robert.burbidge@poptel.coop>]

Can someone clarify the <host> return tag on the <domain:info> command? In
"draft-ietf-provreg-epp-domain-04.txt" page 11, it is stated that <host>
records contain "the fully qualified names of subordinate host objects that
exist under this superordinate domain object".  I can't see the point of
this or how it can be achieved.

Given the following hypothetical scenario:

* The registry is for the ".tld" top level domain
* A client has successfully created the domain "wibble.tld" along with valid
nameservers etc.
* The client performs a <domain:info> query on "wibble.tld".

How can the registry return any information at all that relates to
subordinate objects of "wibble.tld"? Presumably it has delegated management
of that domain to the domain's owner via the registrar, and presumably the
owners DNS system is the only place that holds the definitive subordinate
object listing. Or have I missed  something?

In contrast, I see no problems with returning <ns> objects, as it is clear
that the registry may well have name server information that relates to the
domain. In fact, given the way that <domain:create> works, it's very likely.

Thanks
