RE: Made a list of WCAG techniques to HTML5

At risk of opening can of worms already dealt with, "sufficient" should not mean works with a specific AT product.

My take on ARIA is that the browser and AT implementations are still so varied as to make it a challenging solution for the lowest common denominator perspective, but as a solution for specific known environments may be perfect as long as the product owners recognize the potential ongoing maintenance issues revolving around both browser and At change cycles.

As ARIA browser implementations mature and even out this will move to AT vendor implementations and finally will be a great common denominator for accessibility, but until then my perspective is this has to stay in the use for specific solutions categories at your own risk.

Thanks Mark...

Describedby works on a link in NVDA but for some reason JAWS repeats the heading twice in IE, and doesn't work in JAWS with Firefox... on the other hand aria label doesn't work in NVDA, yet.

The reason I recommend aria label is that the aria label text replaces the anchor link text in the links list dialogue box which is a real bonus for JAWS users... now they can use their tradition list of links are identify the right one... not so with aria describedby.  I dropped a couple of text files after the table. http://davidmacd.com/WCAG/wcag-html5-techniques-review.html

 We don't have an ARIA describedby example on a link in the WCAG techniques yet.

ARIA-labelledby is also sufficient Aria7 , is that then you have to put an id also on the anchor element itself and reference both the anchor element and the heading... because there is concern that a blind user could not identify the link text if someone refers to it... but it certainly sufficient if both refernces are used... just a little confusing and finicky for webmasters who might scratch their head at the aria

Thanks for this very useful work, David.

I would suggest using aria-describedby for H80 and H81, assigning an ID to the
relevant Heading and parent list element.  I think this results in the most
meaningful experience for a screen reader user.  I also think this is a
sufficient technique for H78 as well, given you can identify the fragment of
text that best describes the purpose of the link (could be the Heading, or the
paragraph text in the example given.)
