Re: equivalent
Chaals, as you will know a number of people have championed the need
for multi-media, symbolic, graphical and illustrated equivalents for
text including the need for alternatives at different reading ages,
and synopses, or executive summaries. Whilst this was adopted for a
while, recently this approach seems to have been 'dropped' from WCAG 2.
Furthermore, there is a distinct possibility or indeed likelyhood
that SVG might perform this important role.
I also wrote recently to Chris and yourself regarding this issue, but
failed to receive any response. Also mentioning other relevant
accessibility failings in SVG.
you wrote" I would like to see a couple of the examples of using non-
device-independent events used, and an explanation given of what is
wrong with them (such as the difficulty of understanding how they
will actually work in environments where stylus-based or voice-based
navigation is used)."
However in my opinion there is a need for a whole range of
accessibility techniques, unfortunately Chris considers my expertise
insufficient to warrant assistance.
n.b. http://www.peepo.co.uk maybe one of the first sites
demonstrating tab key accessibility (firefox1.5)

This concept of an "equivalent" (which is not necessarily simply
text) comes from, and is clearly described in the way Will suggests
in the Web Content Accessibility Guidelines [1], which are now a
relatively old, stable and established W3C Recommendation. I think
that the requested change is merely editorial (i.e. it could be done
after the publication of a Last Call draft, in the worst case,
without requiring explicit comment) but that it should be made.
