I was being sarcastic.  That's why I stressed the quotes.  Most web
designers think they know that alt is for tooltips, even though the
handful of the people in the world who understand HTML know that that
is not the intended purpose.

I don't think you can say it is actually incorrect, as, in general,
HTML doesn't say how things should be displayed only what they mean.
(It hints at sensible ways in places.)

Some designers who want a tooltip presentational feature in HTML still
target NS4.

alt is for replacement text when an image cannot be displayed.

title is for additional information.  Non-normatively, it mentions tooltips
as one way that information might be displayed, but there is no requirement
to do so; there is currently no way in HTML/CSS to explicitly request the
generation of tooltips, but there is a big demand to be able to do so.
