-- i woud also like to understand what any
--other object besides a contact needs a roid. Objects such as hosts and
--domains are unique within a registry, maybe we should only have a ROID for
--contacts?

After introducing Client-id's in EPP-02 - which is used for <check> and
<info>
and other transform functions on contact object - the need for ROID is to
satisfy the requirement
of having global unique object id's - currently, they are not used for any
specific
function on objects.
