A good question; in general, the user agent takes responsibility for 
communicating such change to assistive technology. In this case, the 
success criterion would be satisfied automatically.

However, when changing properties of an object in Flash, it is necessary to 
call  Accessibility.updateProperties()  to notify the user agent of the 
changes.

I assume CSS inserted content would be handled directly by the user agent? 
What about JavaScript?
