Can you recommend a version of Firefox and a version of some AT, to 
start testing with?

NOTE: What I am looking for is that the full semantics are exposed as 
long as the element to which @aria-describedby points, is *not* 
hidden.  For example, the element to which @aria-describedby points, 
could for instance be located at the bottom of the page, but without 
being hidden..

Tonight, I have checked, once more, that VoiceOver on Mac OS X Leopard, 
does not - at least not in its default settings - reveal 'full 
semantics', such as links, tables or headings if and when 
@aria-describedby points to a, fully visible, section on the page.
