I agree with Jason 1005. I'd like to add that @usemap on INPUT is  
really the same thing as @usemap on IMG. Its the same feature  
supported in a polymorphic manner. Itt may  not have been implemented  
correctly in UAs, however that can be dealt with by filing bug  
reports. The fact that it's not correctly implemented in UAs may also  
pint to the reason and the solution to why it has not been widely  
used by authors.

If we're going to support @usemap on IMG (and I think we should) then  
we should also support @usemap on INPUT. I often surprised at the  
lack of imagination here, but an obvious use-case for this would be  
to submit form data based on where a user clicks on the INPUT image.  
This could be used in games, it could be used to provide GUI  
selection of items, it could be used in all sorts of ways (if it were  
implemented correctly).

Take care,
Rob
