RE: aria-activedescendant changes to the aria-implementation guide

In today's UAI TF call, we were talking about this topic.

David said that Firefox fires focus events. I don't recall this being
discussed as an option at our meeting two weeks ago, do you? Seems like
this might be the right thing to do since the AT is actually requesting a
focus change.

I agree that an activation event would be the wrong response to an AT
generated focus event. But it is acceptable for those elements where
activate has the same effect as a focus change.

No response for the remaining elements is just as wrong.

But Larry,

If you fire an activation event, it will activate that menuitem when all
the user really wanted to do is move focus to it. That seems more dangerous
than having no effect.

As written, 4.3 specifies that some AT focus events, like focus on a
menuitem, SHOULD NOT have an effect.

To me, this SHOULD NOT be acceptable.

Note: The inability to set Platform focus to an element with the FOCUSABLE
state indicates a Platform accessibility implementation error.

Per Monday's ARIA TF call [1], I have removed bullet 5 from section 4.2 and
modified section 4.3 as discussed. Please review section 4.3 [2] and let me
know if I missed anything.
