That may have been the germ for the idea way back when... (it was
originally called the RENDER attribute, I believe).  But it has since
evolved into a much more general and useful attribute.  I guess the Web
documents just haven't been updated to reflect current ideas about it.  If
style sheets were the original idea that prompted the proposal for the
CLASS attribute, then that's why style sheets are so prominent in the
discussion of its use.
