Re: [regext] Benjamin Kaduk's Discuss on draft-ietf-regext-org-ext-09: (with DISCUSS and COMMENT)

Dear Benjamin,
I found that following sections may be the proper place to restrict the 1-to-1 mapping. I think we can have restrictions in section 3.1 only or in 3.1&4.2.1&4.2.5. I've not decided which one is better and hope to have others' suggestions.

1. In section 3.1 Organization Identifier, add sentences at the end of this paragraph.
A "role" attribute is used to represent the relationship that the organization has to the EPP object. Any given object MUST have at most one associated organization ID for any given role value.

2. In section 4.2.1,
One or more <orgext:id> elements that contain the identifier of the organization. The "role" attribute is used to represent the relationship that the organization has to the object. Any given object MUST have at most one associated organization ID for any given role value. See Section 7.3 in [ID.draft-ietf-regext-org] for a list of values.

3. In section 4.2.5
One or more <orgext:id> elements that contain the identifier of the organization. The "role" attribute is used to represent the relationship that the organization has to the object. Any given object MUST have at most one associated organization ID for any given role value. See Section 7.3 in [ID.draft-ietf-regext-org] for a list of values. 

If we have the restrictions, the 1-to-multiple mapping cases are not necessary to be specified in this document.

Linlin

I won't object to requiring the 1-to-1 mapping, as the impact of the
restriction seems minor.  I am not entirely sure where the best place to
add some text that clarifies this restriction would be; perhaps in Section
4.2.1 where we describe the <orgext:id> elements in <create>?  (I assume
that the formal syntax does not provide for a maxOccurs that applies
per-type.)  It may also be worth a (non-normative) reminder in the <update>
description that the semantics of <orgext:chg> are well-defined because
there is only one entry per role value, but I'm not sure about that.

Thanks,

Benjamin
