RE: LONGDESC - an example

Hence my frustration at, I believe, Internet Explorer for having NO 
indication that a LONGDESC is associated with this pie chart image. MSAA 
also lacks in this information as AccExplorer (unfortunately) clearly 
shows. HPR and JFW are accessing the DOM and then rendering the link for 
the user, which -- in my opinion -- skates the thin line between reader and 
renderer.

I'm not saying that they are wrong; they are providing access which is a 
good thing. I am saying that this sort of "gray area" (who is responsible 
for what) can be frustrating at times during the development process.
