Hi Tim,

Thanks for this work. My comments:

re: "Sufficient" techniques: Probably a good idea (currently our use of 
"Strongly Suggested" is closer to the sense of "Necessary" which is why 
it's not used that much). I'm not quite sure how we make it clear that 
several techniques might be sufficient when used together. For each 
success criteria, would we provide a paragraph describing which 
techniques used together would be sufficient?

re: Technique format:

 > Technique Title (possibly referring to stated success criterion)

I'm not sure how well this would work with our one or two line 
techniques. Unless we expanded all of the descriptions, the titles will 
be as long as the descriptions.

 > Technologies required by the technique and technology features for 
which the technique is applicable

So is this the tool function(s) that we already have or something different?

 > Description (using -ing language to emphasize their informative nature?)


 > Examples

OK - do you see keeping the iconic labels for tool function on these?

 > Resources

OK - I'm assuming this would appear at our discretion since it could get 
very repetitive - remember, we have a lot of techniques compared to WCAG 
HTML techniques document.

 > Testing Information relating to this technique

OK - this will be valuable

 > User Agent Notes

The explanation says: "Which user agents could support successful
accomplishment of this technique" - but aren't the vast majority of 
techniques more or less user agent independent.

 > See Also

Maybe Resources and See Also could be rolled together?
