RE: LONGDESC

Thanks, Jim and Phil.

One of the reasons that a screen reader would not want to do what you 
described below is because, in the utopian sense of the word, a screen 
reader simply reads what is rendered on the screen, and does not perform 
any rendering itself.

In my personal opinion/question, that should be up to the UA as this 
feature is not only helpful to screen reader users but users of non-visual 
browsers, right?
