The Call for Experience regarding the Draft spec XEP-0085 (Chat State
Notifications) ended 2008-10-31. This email summarizes the findings,
with a focus on the three considerations mentioned in Section 8.1 of

1. Implementations.

There are numerous implementations of this specification, including the
Gajim, Psi, Spark, and Transverse clients (which are open-source).

2. Feedback.

We received feedback regarding the implicit discovery algorithm,
specifically whether to (1) modify it by specifying that the User shall
send <active/> in all messages unless it receives a reply with no chat
state notification or (2) remove it entirely in favor of explicit
discovery via service discovery (XEP-0030) or entity capabilities
(XEP-0115). Discussion of this issue is ongoing.

3. Accuracy.

The specification has been double-checked for accuracy by the XEP
Editor, but further reviews would be helpful.
