Comment 337: Limitations of aria-live as defined

Status: Proposal not accepted

Your comment:
There is no way to specify queuing policy. Polite notifications always
queue, assertive notifications always flush. This means you can't implement
the case where you have a series of polite notifications, pause those
notifications, speak an assertive notification, then go back to the polite
notifications. A good example of where this would be needed is a chat room
web app. In the main chat room, the messages in the log are polite.
However, if someone sends you a direct message, you would want that to
pause the notifications in the main chat, speak the direct message with a
different voice, then resume speaking the notifications in the main chat.
Right now, if the direct message were polite, it would be at the end of the
queue, and if it were assertive, it would clobber all the messages in the
main chat.

Response from the Working Group:
We agree there are use cases for the "rude" value. However, we are
concerned that authors might not understand the distinction between "rude"
and "assertive" and there could be widespread implementation that is highly
problematic for users. We also think the handling of this value by
assistive technology needs to be carefully considered. Therefore, we plan
to revisit this question in a future version of ARIA. This is tracked via
our ISSUE-161 (http://www.w3.org/WAI/PF/Group/track/issues/161).

We do think it is problematic if there are assistive technologies that
flush the queue when an "assertive" live region updates. If you aware of
implementations with this problem, we suggest you file bugs with those
