This is my response to comments by both Loretta and Jason-- I had mistakenly sent it to Loretta off-list. So this is my reply to the message she just forwarded to the list...

The quotation below starts with my query, followed by Jason's response: <blockquote> Would there ever be a situation in which something > could happen at the level of the UI that would result in a change of > *role* for the element? If so, does that change have to be available > programmatically as well? I would say yes to both. Suppose part of the u i is replaced in response to a user's action or an external event. The user agent needs to be able to track this change so that the correct role information is presented to the user and appropriate notification can be given. For this purpose, the change does have to be available programmatically; otherwise we get into the situation that used to occur with assistive technologies maintaining off-screen models that weren't always updated when the u i was altered. </blockquote> In a message I sent a few minutes ago, I proposed a rewrite of the sentence in question (the last one of proposal 6 in the 4.2 proposal), as follows: <proposed> Content whose role, state, or value can be changed via the user interface can also be changed programmatically. </proposed> Now I'm even less certain that this proposal "solves" the problem. Seems like the first order of business is to come to agreement on whether role can b changed at the UI level. John "Good design is accessible design." Dr. John M.

Let me try again: <proposal> The role, state and value of every element of the web content can be programmatically determined. If the state or value of an element can be changed via the user interface, it can also be changed programmatically. </proposal> Does this make more sense? This is trying to reflect the UAAG checkpoints 6.1, 6.2, and 6.3, which has a similar requirement. I don't think we ever expect the role to be changed via the user interface.
