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].
