A good point!

It should be made clear in the specs about how ALT text is used.

MSIE 4 handles the TITLE attribute as a tooltip for other tags (like 
SPAN and A). Possibly Netscape and others will add the same in the next 
versions. It would be nice if the W3 specified how an agent should handle 
tooltips when ALT and TITLE exist for the same element.

A LONGDESC attribute would be a good thing (consistent and useful) to add 
for IMG and OBJECT, since it exists for FRAME and IFRAME now.

CSS attributes for handling tooltips would be a nice thing, BTW. It would
be nice to control some font attributes and color of tooltips. Something 
like

  :title {
    font-style: italic;
    font-size: x-small;
    background: white;
    color: gray;
  }

How to assign CLASSes and IDs to an attribute rather than an element in 
CSS I don't know. Has that been thought about yet?
