Hi Loa, Many thanks for your follow-up. Based on your feedback, we have updated the version in the GitHub.
Thanks Regards … Zafar From: Loa Andersson <l...@pi.nu> Date: Tuesday, January 21, 2020 at 9:59 PM To: "Zafar Ali (zali)" <z...@cisco.com>, Brian E Carpenter <brian.e.carpen...@gmail.com>, Ole Troan <otr...@employees.org>, 6man WG <i...@ietf.org>, SPRING WG <spring@ietf.org> Cc: 6man Chairs <6man-cha...@ietf.org> Subject: Re: [spring] 6man w.g. last call for <draft-ietf-6man-spring-srv6-oam> Zafar, Thanks for addressing this. However one thing remains. The text is now: "There MAY be additional segments preceding the END.OP/ END.OTP SID." I don't think there is a need for requirement language in that sentence, I read it as straightforward English: "There may be additional segments preceding the END.OP/ END.OTP SID." Would do very well. Can you explain the need for requirement language? /Loa On 22/01/2020 01:55, Zafar Ali (zali) wrote: Hi Brian, Many thanks for your comments. Much appreciated.

In any case the phrase "MAY or MAY NOT" is not of any normative value. It presumably simply means "MAY" in all cases in this draft.

As far as I can see the sued on I have not used github, I had a couple of attempts to learn the tools, but so far I have failed. I have instead done what I use to do, use the review tool with Word. Since I sometimes have a pushback on the docx-format I save the result as a .txt-file. Drawback is that all comment show up as refrences to a list at the end of the document. But you can't get everything. /Loa PS gives this output for this draft; it is quite a lot and in itself are so much that it is worth sending it bck to the authors and asking them to fix it.
