This comes from a thread on the WAI Interest Group list (obviously...). I don't think that this group is responsible for interpreting section 508 (or anyone else's guidelines) beyond actually ensuring that we understand what the requirements they chose were, why, and whether we agree or disagree with their reasoning. On the other hand, the fairly sound practical idea that we should be indentifying techniques and technologies fits solidly into our scope - it is one of the things we are working on. So I thought this made a good jumping-off point for people working on techniques related to dynamic content.

It is clear, for reasons already mentioned in this thread, that 508 does not require that your page function with JavaScript turned off. Therefore, for 508 considerations, I believe the discussion of Lynx and down level browsers is off the table. Like Reidy, my interpretation of the 508 JavaScript standard (1194.22 (l)) is that the result/effect of JavaScript must be accessible, i.e., available to assistive technology. So indeed, accessible JavaScript techniques will help - but perhaps the most important contribution we can make is to agree to and describe uses of JavaScript that DO NOT satisfy (a strict interpretation of) the section 508 standard. Here's my first candidate for JavaScript that DOES NOT meet the 508 Standard: ** Do not use the OnChange event handler to trigger ACTION in a select menu. If you do, the menu will not work with the keyboard. Note that the OnChange event can be used for other purposes, like changing the state of a check box. If onChange is used, focus remain on the select menu. How do we define actions that are OK and ones that are not?

Goodbye." >Surely that's not what they mean?! > AG:: Just as it is easy to read 'identified' in a way that is too loose, it is easy to read 'equivalent' in a way that is too tight. We have had lots of problems with people not grasping the optional [rough] implied where we talk about equivalents. What is really intended in either case (WCAG or 508) is something in the middle where the stretch to describe it either way is just a little stretch. If we can build a good corpus of good examples, I don't think that we will have a lot of trouble getting those who are trying to comply with 508 to emulate the examples.
