Thanks, Marti, for putting the finger on the key accessibility issue
for people with attention-related perceptual deficits, such as
myself. Repetitious (or other irrelvant) content is just as effective
in disabling people like me as lack of text (or lack of illustrations)
would be in disabling people who require [text|illustrations|etc].

I've been disabled many times by web sites whose ALT text was a
_description_, with irrelevant details, instead of _replacement_ for an
image. This was an accessibility defect in the old content guidelines:
the old guideline said "description" instead of "replacement", and
webmasters who were trying to comply were led, instead, to disable
potential users like me.

I've joined this list to prevent analogous defects in the next version
of the content guidelines.  It is a wothwhile effort to provide
illustrations, audio, etc etc for those who need them. Just make sure
that those extra versions of content can be avoided by those of us who
would be disabled by the redundancy.

Context matters. Seldom does *anything* have only one cause.
