Re: [alto] I-D Action: draft-ietf-alto-incr-update-sse-18.txt

[Jensen Zhang <[e-mail]>]

Dear Vijay, Jan and ALTO WG,

After some good discussions with Richard, we worked together and finished
the latest revision (-18) of the SSE document. The revision addresses
issues from Vijay's and my previous feedbacks [1][2] with updates as listed
below.

- Clarified terminologies
  - Defined Substeam-ID and Data-ID in Section 3 before they are first used
in Section 6
  - Updated section 6.1 and section 6.2 to make the format of data type
SubstreamID clear
- Extended examples
  - Added a new example to illustrate how SSE provides updates for the ALTO
resource returning a multipart response
- Updated recommendations in the consideration section
  - Renamed Section 10.1 to "Considerations for SSE Text Formatting and
Processing" and moved it to the end of Section 10
  - According to Vijay's comment, rewrote the considerations for SSE text
formatting and processing from both viewpoints of the client and the server
- Fixed nits and accepted rewording suggestions from WG reviews

As Richard suggested, I was added as a contributor to the latest revision.
Thanks, Richard!

We would like to say the current SSE document is ready to go. If you have
any suggestions, please feel free to tell us. Any feedback will be welcomed.
