I read your suggestion such that it was perfectly fine to invent a language regardless of if it had any User Agent Support as long as it could be accessible, I don't see that that makes sense, and it should only be where existing technologies do not already do the job (MathML is an existing technology.). A new language should only be invented if it can be shown that there does not exist one that achieve it's aims (even with minor modification - UA support is much more likely in this situation). Continued Re-invention is very popular amongst W3 groups it would seem, it's not constructive though, and on accessibility, having user agents that understand it is key to it being accessible. > > The language doesn't hide anything, the (incompetent?) script authors > > choose to hide it, there is a distinction in my mind at least. > > MM > Not to me.

In what way is javascript not designed to work with assistive technologies, what specific areas are at flaw? Sweeping statements don't help - I assume mainly you are discussin the User Agent Object Model rather than the language, if so, should you not be addressing the HTML/DOM working groups with some urgency on the issues? > MM > What JavaScript does is pretty basic compared to what CC/PP will do.

I see no UA support for CC/PP and Personally am not convinced of the need, or the desirability of allowing content negotiation on such terms, probably because I've seen the failure of existing content negotiation based on User Agents. However javascript detection is still probably more reliable than CC/PP as that relies on accurate information from the User Agents being given, something that's never done - indeed it's often intentionally lied upon because of content-negotiation, but this is in anycase not for this list. > old MM > > > It can also provide good usability gains: most search > > > engines use it to focus on the search text input. > JL > > This is not a usability gain > > MM > To most people, it is. That's no answer to my detailed explanation of the problems with using the technique. Jim.
