Hi Jon.

Now you are talking. Yes, there could well be a need. We already have
text 
and graphics which are overlaid over a background color or
texture/image. Transparency is the obvious next step - real variable
translarency, not 
some on-off hack. 

Not in 3.2, obviously, or even necessarily in the HTML DTD, but HTML 
documents might well benefit from an alpha plane.
