Hi Roland,

Thanks for submitted and sharing both the baseline and the version with the intended changes.
I do not have any technical concerns with the changes, but I do have a couple editorial suggestions.

Section 2.2
---
OLD
Modify statement that P-Visited-Network-ID header field can appear in all non 100 (Trying) responses.

NEW
Add statement that P-Visited-Network-ID header field can appear in all non 100 (Trying) responses.
—

I suggest this because no statement about responses existing previously, so a statement is added rather than modified. 


Section 3
---
OLD
The P-Visited-Network-ID header field can appear in all SIP methods except ACK, BYE, CANCEL, NOTIFY, PRACK, INFO, UPDATE and in any SIP non-100 response message .  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.

NEW
The P-Visited-Network-ID header field can appear in all SIP methods and non-100 responses, except ACK, BYE, CANCEL, NOTIFY, PRACK, INFO, and UPDATE.
—

I suggest this wording because it aligns with that in RFC 7976 for P-Access-Network-Info, P-Charging-Vector, and P-Charging-Function-Addresses. Justification for not including in 100 responses seems unnecessary and is not provided for the other P-headers in RFC 7976, so for consistency here as well I think it is best to leave it out for P-Visited-Network-ID.

Cheers,
Charles

Then the next version should include all the desired changes. Doing it this way will help reviewers (and implementers) to easily see what is really new without being distracted by all the boilerplate and formatting changes needed just bring the old rfc up to current conventions.
