Thank you for the explanation Becky.

Not providing this example now does not mean that WCAG 2.0 will prevent any
new DHTML accessibility technologies in the future.

I am simply wary of providing examples of techniques that are not supported
by at least a majority of current assistive technologies and/or that cause
issues currently for one or more disability user groups. Current support is
a topic that gets raised constantly - even in today's teleconference.

Apart from lack of screen reader support (JAWS, Home Page Reader and Hal),
how is a sighted keyboard user to navigate to a link within the content of
a panel? With current technologies this would be with the tab key, but in
the provided example it would instead shift the focus out of the tab panel.
Currently, using an up/down arrow would scroll the page and not move
through links. I think this is too confusing for most people to include

The ability of implementing such a technique may change with time (as you
have indicated), and at that time I would support its inclusion in WCAG
techniques. For now I do not think it should be included - or it should be
made very clear that it is a possible future technology implementation

I think this use needs further investigation for screen reader users. The
left- and right- arrow keys are used to step through words by JAWS for

This example [1] was created using the Dynamic Accessible Web Content
Roadmap [2].  It is fully supported by WindowEyes 5.5 and Firefox 1.5.
While this example may not work with all assistive technologies today, my
intent is to make certain that these new DHTML accessibility technologies
are not prevented by WCAG 2.0 when they become more widely supported.
