Description Daniel Trebbien 2015-01-11 23:00:29 UTC 
http://www.w3.org/TR/wai-aria-1.1/#alertdialog states:

> Authors should use aria-describedby on an alertdialog to reference the alert
> message element in the dialog. If they do not, an assistive technology can
> resort to its internal recovery mechanism to determine the contents of the
> alert message.

I think that this needs to be clarified so that if the author specifies 'aria-describedby' on an alertdialog, then an assistive technology MUST use the author-provided description instead of resorting to its internal recovery mechanism.

I am seeing, for example, that JAWS 15.0 is resorting to its internal recovery mechanism in Internet Explorer instead of using the 'aria-describedby' description.

Test case

This demonstrates the issue.  In JAWS 15.0 / IE8, 9, or 10, when the "Show Dialog" button is activated, JAWS announces "This should be hidden".

Sorry, I uploaded the wrong version.

We cannot specify AT MUST rules.
