Re: I-D Action: draft-ietf-simple-chat-17.txt

Hi:

So, the long awaited version -17 of the MSRP chat draft has been posted. 
This version addresses all the comments received in the IESG review and 
various directorates that also took a look at the draft. Among others, 
these are the most relevant changes.

- Added definitions of "identifier" and "to log in".
- New Section 4.1 lists all the Policy Attributes of the chat room in a 
single section.
- Clarified that congestion can occur due to the chat room application or 
due to some other application.
- Clarified that the MSRP switch should learn the recipient's 
capabilities through the 'accept-wrapped-types' in SDP. Procedures as for 
what to do if the MSRP switch is aware that a recipient does not support 
a given media type.
- Quite a few clarifications around chunked messages. It was clarified 
when the MSRP switch has to delete the temporarily stored state. Also, 
how to deal with situations where the connection is broken before the 
reception of the last chunk.
- Added a length limit to MSRP nicknames: they must be between 1 and 1023 
octets, after UTF-8 encoding.
- Fixed a bug: the error result code is 425 rather than 423 in the examples.
- Added more security considerations around the usage of TLS, policies to 
preserve a nickname once the use logs off, confusable nicknames, 
rendering of nicknames that contain scripts or code, and anonymity when 
using TLS with certificates.

 From the authors' perspective, we believe the draft is ready. I will 
contact the IESG members to verify that the current version satisfies 
their comments.
