Comments on this draft: On 4/10/23 1:51 AM, Brian Rosen wrote: > This message starts a two week working group last call for draft-jesske-update-p-visited-network-03. Please review this (short) document and send comments, positive or negative to the list. I have no problem with the substance of this document. But I think the form could use improvement. In particular: 1) RFC7976 was very clear in exactly how it changed 7315, by having "Old Text"/"New Text" showing an entire altered paragraph. Hence an implementer has clarity about what is to be implemented. This new document isn't as clear. It says the following in section 3: In [RFC7976] section 3. "Updates to RFC 7315" the P-Visited-Network- ID header field was restricted to the following: The P-Visited- Network-ID header field can appear in all SIP methods except ACK, BYE, CANCEL, NOTIFY, PRACK, INFO, and UPDATE. This document allows the use of the P-Visited-Network-ID header field additionally within Responses as follows: Any SIP Response message, except for a 100 (Trying), MAY contain a P-Visited-Network-ID header field. The P- Visited-Network-ID header field is not needed in the 100 (Trying) responses, since they are transmitted hop by hop, not end to end. I infer that it is saying to add text to [RFC7976] section 3, presumably within the paragraph following "New Text". It isn't explicit about exactly where to add that, nor if the addition is to be one sentence: Any SIP Response message, except for a 100 (Trying), MAY contain a P-Visited-Network-ID header field. or two sentences: Any SIP Response message, except for a 100 (Trying), MAY contain a P-Visited-Network-ID header field. The P- Visited-Network-ID header field is not needed in the 100 (Trying) responses, since they are transmitted hop by hop, not end to end. Instead, I suggest that this new doc provide a newer revised version of the complete text of section 5.7 of 7315. I'm not sure if it is better to state this directly relative to section 5.7 of 7315, or relative to section 3 of 7976. 2) This doc is flagged as Updates:7976. But 7976 updates 7315, and the changes in this doc alter to changes to 7315. So this doc should also be tagged as updating 7315. Or, it might be sufficient for it to only update 7315 and not 7976. 3) IdNits reports a few small things that should be addressed. Thanks, Paul
