Hi al,

ATs have been playing on this aassumption for quite ssome time now.   
IIInfact, they will go so far as to repair something that is missing  
or incorrectly coded in order to optimize the user experience or so  
they hope.  This also is part of what configurability is based on.   
for instance and this may not be the best example, I can have  
displayed <spoken> the uri of an image, its name or the surrounding  
text or whatever is longest or nothing or "graphic" using jaws.  This  
may be mixing things a bit but it should provide the info sought.   
I'll have to try out the q ccommand in firevox.
