When I came to Vancouver to discuss how to complete the draft, it was also my understanding that the involved parties could live with an informative note, thus I support Vijays conclusion. 

I'd like to add that while [1] and [3] are easy nits, on [2], there are some further comments from Keith + the fact that we have moved to an informative note, thus I'm not that sure how much that is left of this comment.

Note also that if the current authors cannot find time to complete the work rather soon, I still have the backup author - Roland Jesske. I assume that Vijay will contact him if necessary. I would hope that 3GPP does not need to wait for too long for completion. I'd propose to give people time until end-of-the-week to revise the draft.


On the IANA-registry, I have nothing against this as long as it is formally correct with the current phrased note by Vijay and doesn't cause more work to the draft and/or delay the completion process. However, IMHO we shouldn't restart the debate if IANA-registries isn't possible without normative statements in the drafts.

I think it might be wise to indicate in the IANA registry that the value "isdn-network" is reserved for historical reasons and its use has been deprecated.

The WGLC for draft-ietf-cuss-sip-uui-isdn is now over.

Below is my personal interpretation of where the matter stands, i.e., what I write below is not written as a co-chair but rather to determine if the WG agree that this is where matters now stand.  Please comment if I deviate from what you all agree.

- "isdn-network" is tacitly supported, but not overtly so.

- More specifically, "isdn-network" is not IANA registered, and all
   text related to it is not normative.

- The addition of the Note uses non-normative language, i.e.,

      "The 'isdn-interwork' value for purpose parameter was used
      in Internet-Drafts that have led to the publication of the
      present RFC. Although these documents had no other status than
      "work in progress", this value is implemented by some vendors.
      Therefore, it is recommended to support parsing and interpreting
      'isdn-interwork' the same way as 'isdn-uui' when receiving

Is this an accurate representation?

Now back with the co-chair hat on ...

There has been reviews of the draft [1,2,3] by key WG members.  Can the draft authors please comment on next steps with respect to revising the draft.  Enrico and I will start the shepherding step in parallel to the revision to be submitted.
