Yes, I think we would provide a note referencing other sufficient 
techniques in the list (or possibly in another list).    I think that it 
may not be necessary to combine several techniques together for 
sufficiency, depending on how the techniques are worded.   I think that it 
would be simpler to just list the sufficient techniques for each success 
criterion if possible, without any regard to grouping,
but if it is necessary to group, then appropriate notes should be added.
(NOTE: The WCAG Guide Documents describe options or scenarios, which then 
sufficient techniques, but I'm not sure this is necessary for our work? 
(adds another layer?))

I was thinking of something really short (for example) for success 
criterion A.0.1, just titling the first technique in the list "Technique 
A.0.1-1 (or something like that to uniquely identify the technique and 
allow for filtering/searching - maybe also an identifier for sufficiency, 
like A.0.1-1s?)

The AUWG could discuss this (WCAG has baselines, which are comprised of 
technologies - WCAG definition).   I think we would need to include any 
prerequisites/requirements necessary in order
to successfully accomplish the technique (may relate to the AUWG 
discussions on definitions of terms?).

The AUWG could discuss.   What unique purpose (not served by anything else)
do the labels serve?   Are there any disadvantages to use of such labels?
Would they be confused with icons?    QASpecGL talks about labels for each
part of the conformance model (ATAG2.0 has Levels A, AA, AAA)

Yes, at our discretion.  I think that to successfully accomplish a 
technique, if an offerer wants to find out more
information in relation to such accomplishment, and such relevant 
information (approved by the AUWG according to criteria set) is available, 
then that information should be referenced from that

The AUWG should discuss - I think a goal for "general" techniques is to 
make them independent of any such requirements (wider applicability?), but 
if there are "technology" (user agent or other) limitations/constraints 
applicable to a technique, we should make those known (technology-specific

Sounds good.
