Hi Kent,

Thanks for the review.

Yes, this is over RESTCONF so http1.1/http2 are both ok. One change<https://www.ietf.org/rfcdiff?url2=draft-ietf-netconf-restconf-notif-08> which was done ~8 months ago is to have 1 callflow “over RESTCONF/SSE” as opposed to the previous separate callflows for http1.1 and http2. The reason http2 is mentioned in a few places is because of http2 streams. Section 4 already mentions “where HTTP2 is available to…”, so it looks like section 3.4 is the only place missing “when HTTP2 is used”?

I’ve corrected the nit below, will be in next revision.

Regards,
Reshad.

Hi Reshad, Thank you for continuing to follow through on getting this draft over the line.

One thing I noticed in the latest diff is a leaning towards HTTP2 but, AFIAK, dynamic subscriptions should work over HTTP1 as well, right?  If so, then I think that some text is needed to say this.  Currently only Appendix A mentions "HTTP1.1" in an aside sort of way and the first "hit" for "HTTP" is for HTTP2 in the Terminology section.  Section 3.1 (Transport Connectivity) references RFC 8040 Section 2 (Transport Protocol), which leads me to think that any RESTCONF connection is okay.  Maybe what is needed is that, wherever HTTP2 i mentioned, it should say something like "if HTTP2 is used" or "when HTTP2 is used" - does that make sense?

nit:  s/can not be 2/cannot be two/
