ARIA should require DOM mutation event support for compliance.

Section 6.2.3 already requires support for the author to make  
arbitrary elements focusable.

And the aria-activedescendant property definition already implies that  
authors should be able to monitor DOM changes made directly by the  
assistive technology or user agents. "Authors SHOULD capture changes  
to the activedescendant property, which can occur if the AT sets focus  

So the ARIA spec should require implementing user agents to support  
DOM mutation events.
