Dear WG,

Thanks a lot for those who already sent comments to the authors! As an
important service, this document can benefit from in-depth reviews, as
Vijay pointed out.

The main substantive comment so far is on clarifying the coupling between
the Update Stream Service (USS), which will be used by the network to send
SSE Update Messages to a client, and the Update Stream Control Service
(USCS), which will be used by the client to control the server, by sending
add/remove of resources messages. In the current design, SSE update
messages can provide the final outcome of a control request. The comment
was whether this is a generic design.

After extensive discussions among the authors, we propose to make the
following revisions---these revisions will be simple and clean, and if
approved by the WG, they can be updated right away:

M1. The document clarifies that USS uses a *modular* design, in that the
Update Stream Service (USS) is a modular service. Hence, it can be
controlled by not only USCS but also other potential control channels, such
as a private control protocol. Hence, the messaging of USS, in particular,
its Control Update Messages, should be (slightly) revised to reflect this

M2. The document clarifies that USS uses a self-contained design, to take
advantage that current design can be simply, elegantly extended to also
report error updates.

The authors request that the WG approve these edits so that the authors can
proceed to submit a revision shortly, in just a couple days.

Of course, the authors will also wait for other comments, until the July
4th closing, to make a single, coherent edit.

Thank you so much!
