giftie gie us 

  To see oursels as ithers see us! "

      Robert Burns, "To A Louse/On Seeing One on a Lady's Bonnet at
Church" 


For me, the most useful tool for making an accessible web page would be a
presentation that showed the "normal" page and the accessible
alternatives at the same time, with a way to edit the accessible content
on the same display.  For example, 


- showing editible ALT text next to each image

- for LONGDESC, displaying the pointed-to content in an editable form

- for image maps, showing the ALT for each AREA, again in editable form

- for videos, seeing the captions, while being able to freeze and edit
them

- for applets or objects, seeing an editable alternative simultaneosly in
another window

- for frames, seeing an editable no frames version simultaneously in
another window



And, more ambitiously,


- For a whole page, seeing, or better yet, hearing the text version as it
might sound on a screenreader.  E.g., something like lynx, or the text
display you get with pwWebSpeak.  Also, there should be a way to see
which point in one presentation corresponds to a point in another.  For
example, when you highlight content in one presentation, it gets
highlighted in the other.


- for portions of a page labeled by a CLASS, the name of that class: plus
a way to change

  that class name consistently thoughout all pages.  (This assumes that
in the future the CLASS name will be accessible text, so it must be
something mnemonic and descriptive (cf.
http://lists.w3.org/Archives/Public/w3c-wai-er-ig/1999Sep/0054.html and
other email in that thread). 


This is useful because:


- It better suits at least some people's thought processes to design the
"normal" version first and add the accessible content later.   This way
you can devote full attention to the alternative content.


- In fact, in some commercial settings, different people compose images
and text, and it would be the best for the people most skilled in text to
supply the alternative content.


- It's a quick way for the author  check of what was done.




This is somewhat implied by 3.1, to prompt the user for accessibility
information. However, "prompt" implies a box that pops up when inserting
the image or other content, which is different than what I'm suggesting
here. It's also suggested by checkpoints in Guideline 4, to provide
methods for checking and correcting accessible content.  However, this
section starts off by talking about "alerts" and "highlighting problems"
which implies the sorts of problems that can be spotted automatically. 
The presentation I'm suggesting address problems that wouldn't generate
automatic alerts, since they depend on human judgment (e.g. checking that
ALT the alternative content is meaningful and helpful).  Also Appendix
section 3.5 on "ALT text for the IMG element" offers a version of the
document with ALT text instead of the image, but not alongside the image. 


So I'd suggest adding the editable presentations suggested above as an
additional checkpoint under guideline 4.  I'd personally give them
priority 2.
