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?

To be clear about one of the points in the review, MAY NOT is not
allowed by RFC2119 because it is totally ambiguous in English (since it
can mean either "must not" or "might not"). 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.
Regards
Brian

WG,
I have reviewed the entire document.
First, I'm not an IPv6 expert.
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.

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. Was the noits tool checked at all before starting the wglc?
