Thanks, and if you find a suitable spot in one of our wikis that'd be 
great (if not already there somewhere). Also maybe also overviews of 
what accName/accDescription are - most designers don't think on this 
level at all.

<chair hat off> Maybe, maybe not. We really have to discuss these things 
on a case by case basis. Accessible development techniques and UA 
support are always changing, so some caution is needed - (this is part 
of the reason we are having this unforeseen @alt debate, no?). Ideally, 
the standard should define the behaviour but as we know in practice 
that's just not always the case.
