I'll slowly be commenting mostly on a section-by-section basis.

These are my comments regarding section 1 of XEP-0301: Real-Time Text.  There might be some mention of these earlier, but I've lost track.  If already addressed previously, then please ignore.

First, this section is written more as a marketing pitch and less as a technical description.  This bothers me enough that I strongly urge it be changed.

Specific suggestions:

* I think paragraphs 1 and 2 can be merged, in their current progression.
* De-emphasize the first sentence of paragraph 2. I personally do not see any technical reason for this call-out.
* Reword the paragraph 3 in terms of the problems it is solving. One possible suggestion:


While XMPP CORE [RFC6120] and XMPP IM [RFC6121] provides for near real-time text conversation, this is often as sentences or sentence fragments that convey complete thought on the part of the sender, in a linear progression, as the user directs. However, it is desirable to also provide to recipient clients the text as it is entered by the sending user. This behavior is particularly important for emergency situations or for speech-to-text transcription.


* Make a final paragraph about the previous implementations and where to find more information (eliminating the duplicates from other paragraphs). One possible suggestion:


The concept of real-time text is not recent.  Previous technologies that provide this functionality include:

* 'talk' command on UNIX systems [citation recommended]
* Teletypewriter (TTY) and Text Device for the Deaf (TDD) telephones [citations recommended]
* [RFC4103] and [ITU-T T.140] for Session Initiation Protocol (SIP)
* [Real-time IM] feature within AOL Instant Messenger (AIM)
* A component of Total Conversation, which is part of Responding to All Citizens needing Help [REACH112]

More information on this concept, including visual presentations on its use, can be found at [Real-time Text Taskforce].
