I have reviewed this document.  I believe it close to being ready.  I do
have three comments:

(1) Section 1.1
There was an interaction in July 2020 about describes why subscription state
change notifications are not included within the draft.
https://mailarchive.ietf.org/arch/msg/netconf/K0jnMW3GZknxihnNjKL4UlFTfoY/
https://mailarchive.ietf.org/arch/msg/netconf/CYOosxZy_-tKKsrCCoLmQeFvEuI/
Actually, we are talking only about a subset of the subscription state
change notifications, as <Subscription-Started> is include within examples
of this document.  

Per Alex and my earlier requests, it would be good to include which state
change notifications are included, and why,  so that others have this
context.  This would allow receivers to understand that the control plane
messages which identify the current state of the subscription on the
subscriber are not available.  Perhaps it might even drive others who might
want this functionality to add this upon the current http-notif.  This might
be worth including in Section 1.1, Applicability Statement.

(2) Section 2.1
Learning Receiver Capabilities is critical, as Configured Subscriptions can
DOS a receiver if adequate protections are not on the publisher.  It would
be useful to list this here so that the topic is not missed in an
implementation.  Alternatively this could be addressed in Section 5.

(3)
In Sections 1.5 and 8.3 there is a reference to
I-D.ietf-netconf-notification-messages.  I am not sure how this impacts the
eventual completion of this draft, but defer to others who know the IETF
process better.

Thanks,
Eric
