Try RFC 8225, Section 9, perhaps?  Ken.

Not sure I understand the has-no-choice part. Where is it said that the claims must be ordered in alphabetic order? We could for sure specify it that way, but based on your e-mail it seems like it is already specified somewhere?

Regards,

Subject: [stir] PASSporT extensions: order of claims

Hi,

Section  says:

   “Specifications that define extensions to the PASSporT mechanism MUST
   explicitly specify what claims they include beyond the base set of
   claims from this document, the order in which they will appear,…”

When looking at the extensions we are currently working on:

draft-ietf-stir-rph-03
draft-ietf-stir-passport-shaken-01
draft-ietf-stir-passport-divert-02

…I don’t see anything about the order in any of the documents.

I think it would be good to have a dedicated “Order of claims” section, or something similar, in each extension specification.

When looking at the examples in the drafts above, it seems like even the base claims are in different orders. Not sure whether there is an explicit requirement that they need to be in order, thought.

Regards,

Christer
