Hi, Sailesh,

Thanks for a very thorough reply.  I guess the question that still 
remains is "do TFOOTs require association markup; and if so, is there 
some simple way to attribute SCOPE to them, without having to add all 
the ids and headers?"

John, the tool we are using is our own internal concoction (Oracle 
Accessibility Checker), and it currently identifies the TFOOTs as being 
in a data table and lacking some kind of associative markup.  So, we are 
not only trying to figure out what the accessible HTML would look like 
for such a table, but also trying to incorporate that into our tool.

Thanks,
-Kerstin
