This document has been reviewed as part of the transport area review team's
ongoing effort to review key IETF documents. These comments were written
primarily for the transport area directors, but are copied to the document's
authors and WG to allow them to address any issues raised and also to the IETF
discussion list for information.

When done at the time of IETF Last Call, the authors should consider this
review as part of the last-call comments they receive. Please always CC

I reviewed this in conjunction with the set of related WG documents on
NETCONF/RESTCONF subscriptions and event notifications.  I also have some
comments on other documents in the set, some of which may influence this once,
since they are closely related.

In figure 3, and text on page 11, there is an example with a DiffServ codepoint
value of "10".  This could be interpreted as binary, decimal, hexadecimal, etc.
 It should be clear what the base is supposed to be.  It seemed pretty
ambiguous in this and the related documents, so it's not apparent that an
implementer would be sure to get it right or for it to be compatible.

I have other broad comments on the DSCP usage that will be in review comments
for the subscribed-notifications draft where it is more appropriate.
