Frank,

When looking at your pages and the accessibility of such, I would recommend
sticking to a set of guidelines that meets your orgainization's and
audience's needs. You have Section 508, W3C-WAI, IBM, and other guidelines
available to choose from, yet they might be contradictive. As this case
with Macromedia vs WAI. I wouldn't read too much into some of the
guidelines, because that is what they are, just guidelines. Even when you
check pages with different HTML validators, you typically get different
results.

If your flash is purely decorative and the page and is insignificant as far
as content, I would see no problem with keeping it. I would, however, keep
in mind the flicking and the potential cause for triggering seizures.

mark,

thanks for your reply. what do you think the situation would be with
a purely decorative Flash-based element that moves but does not contain
any essential information?

Would the design have to omit this feature in order to comply with
this WAI checkpoint (even if it were made accessible according to
Macromedia's guidelines).

Regards
Frank Gaine
