Re: Questionable implementation of IMG ALT attribute as tooltips

Apologies if it's just me that didn't receive it...]

You are correct if you consider the image element on its own: however,
when taken _in context_ the ALT text here is *superfluous* to the
message, since when the image is unavailable the message reads:

 "Warning: Warning:This must be done by a qualified technician."[1]

The description of ALT quoted above is that it is an _optional_
_alternative_.

Since the word "warning" already appears in the text, adding it again as
ALT text is redundant.

Consider these two alternative examples which might have been used
instead.

Optional:
   Warning: <IMG SRC ="triangle.gif" ALT=""> This must be
   done by a qualified technician.

Alternative:
   <IMG SRC ="triangle.gif" ALT="Warning: "> This must be
   done by a qualified technician.

I agree with Jukka: the author of that ALT description didn't really
_mean_ what s/he said - or, worse, didn't understand the implications of
what was being written :(

So, getting back to my original point (about the inappropriate use of
ALT text as tooltips), does the above indicate that there is indeed
ambiguity in the specifications as to the purpose of ALT?

I repeat: If so, I move to resolve them.

[1] Of course, it should read "Danger! Will Robinson..." (sorry, just
trying to inject a little humo[u]r here).
