COMMENT:
----------------------------------------------------------------------

Section 4:

Based on the QoS discussion for draft-ietf-netconf-subscribed-notifications
weight is not really a a priority in the terms people think of it. It only
provides a weight for bandwidth allocation.

   o  take any existing subscription "priority", as specified by the
      "weighting" leaf node in
      [I-D.draft-ietf-netconf-subscribed-notifications], and copy it
      into the HTTP2 stream weight, [RFC7540] section 5.3, and

I would recommend that the use of "priority" is reformualted here to reflect
that aspect.

   o  take any existing subscription "dependency", as specified by the
      "dependency" leaf node in
      [I-D.draft-ietf-netconf-subscribed-notifications], and use the
      HTTP2 stream for the parent subscription as the HTTP2 stream
      dependency, [RFC7540] section 5.3.1, of the dependent
      subscription.

What is not obivous to me is that just because that a subscription exists at
the publisher that it is going over the same HTTP/2 connection and thus there
might be nothing for the dependency to point at that is relevant for the
mechanism described in RFC 7540. I didn't even find a recommendation that the
receiver (subscriber) should actually re-use the HTTP/2 connection for all
communication with the same publisher.
