Hi Lionel,

Now I see the purpose for the clarification, which is helpful.
Therefore it could be sufficient IMHO to have:
As a reminder, the IETF RFC 3588 does not define a new Diameter base protocol but is a new version of the specification defining the Diameter base protocol. The IETF RFC 3588 is obsoleted by the IETF RFC 6733, as defined in the IETF RFC 2223:

    Obsoleted-by

       To be used to refer to the newer document(s) that replaces the
       older document.

Which already make it clear that documents using obsoleted IETF RFC should be  updated to refer to the new IETF RFC when published (i.e. applicable to both RFC 3588 and RFC 4006 as well), and also that per 3GPP LS it is already assumed “the normative reference for Diameter base protocol would be updated to IETF RFC 6733 for 3GPP SA5 Diameter charging applications”.

Besides this, don’t you think it would also be useful for 3GPP to get recommendation on how to address the temporary situation whereby 3GPP application(s) will refer to the new version RFC 6733, whereas the current RFC 4006 is still refered-to ?
What about to have some statement like?:
"Whenever a document is updated to refer to the new IETF RFC 6733, if the same document is also using IETF RFC 4006, IETF DIME WG recommends to ….. until the revision of the IETF RFC 4006 aligned with IETF RFC 6733 is published.

Dear Maryse,

The clarification is intended to clarify the wording "new Diameter base protocol" used incorrectly in the LS and then clarify the notion of "obsoleted-by" used by IETF and the consequence on documents referencing the obsoleted RFC. And the 3GPP charging specification refers to both RFC4006 and RFC3588.

To make the recommendation clear, would the following rewording be acceptable?:

"any document using the IETF RFC 3588 as reference for the Diameter base protocol should be updated to refer to the new IETF RFC 6733. Therefore, as a general guideline, the IETF DIME WG recommends 3GPP WGs to follow this recommendation in their specifications when applicable. The same recommendation will apply for the revision of the IETF RFC 4006 when published by the IETF as for any new RFC obsoleting an old RFC."

Regards,

Lionel

The aim of this update is to align the Diameter Credit-Control application specification with the IETF RFC 6733, fix existing known issues in the current specification and comply with the recommendations given in the IETF RFC 7423 on the design of Diameter application. The time line for the completion of the RFC 4006 update is set to November 2017.
