This is a really excellent document.  I need to re-read it a few more 
times to fully digest it.

I would really like to see much of this text adapted to be part of our 
final document deliverable, as it gives so much more context and 
understanding to readers of what we are are doing and why - far beyond 
the too little we gave in the first public draft of "applies directly as 
written... replacing "web page" with..." + occasional notes.

I remain concerned with how things would sort out in practice for our 4 
unresolved SCs, particularly for software.  I want to review some of our 
with this approach, and see how that feels (e.g. Bypass Blocks - what is 
"repeated content" in software that would be bypassed?  What constitutes 
a software title that describes the topic or purpose?  Is "Skype" or 
"Pidgin"  "Adobe Acrobat 9 Pro" or "NetBeans IDE 7.0" a title for 
software that sufficiently "describes the topic or purpose"? (of four 
random apps on my computer at the moment - which respectively do IM and 
audio and video conferencing, IM via a bunch of different protocols than 
Skype, read & author PDF documents, and a developer tool for creating 
any of a huge variety of types of programs)? ).

I also remain concerned with how the white paper treats Conformance.  
Our work statement directs us to describe "the extent to which WCAG 
Conformance <http://www.w3.org/TR/WCAG20/#conformance> /*is meaningful 
*/to non-Web ICT" (emphasis added). Yes/No evaluation software support 
for the individual SCs is extremely difficult.  One cannot test all of 
the UI permutations possible in many software situations.  Yes, this 
situation isn't unique to non-web software; it also arises in web apps.  
AND we are seeing EvalTF struggling with that very question, and heading 
now in the direction of a report of what was found rather than a simple 
Yes/No evaluation.

I continue to believe it is not only appropriate - but also within our 
remit as stated in our Work Statement - to go beyond finding word 
substitutions for determining "what WCAG 2.0 Conformance means in the 
context of non-Web ICT".

I will try to provide more detailed feedback on the various sections of 
your otherwise excellent white paper in the survey for tomorrow.
