But what about when there is no technical standard that applies? Or what
about if you've applied them all but the product is still not useable? I
think that all the standards have to be taken in total. I think the
technical standards can be used to show in part how you propose to meet the
functional criteria. But when all is said and done, I would argue that we
could merely follow hte functional criteria and drop the technical
standards. Of course no one is really prepared to do that, but the
funcitonal standards are trying to capture what should be occurring.

Subject: [teitac-general] Applicability of Functional Performance Criteria


Some of the discussions during the call today and especially the examples
seem to be incorrectly founded in the premise that the functional
performance criteria provisions always need to be applied. There were
several examples or scenarios of Web, Kiosks, and other applications that
went something like this:
"The Software and Web provisions already apply here, so why do we need to
also apply this "functional criteria" if we already meet all those
Software & Web provisions? Shouldn't the functional performance criteria
only apply when choosing not to comply with the applicable software and
web provisions for a software or web application?

If we took the view of only applying the functional performance criteria
when not choosing to comply with the other applicable provisions, then we
wouldn't be discussing the "AT used by people with disabilities" clause.
If there are some other necessary provisions, then lets discuss them. But
if we continue to promote this "catch all" provision as also applying, we
will continue to have this unproductive discussion. Why can't we just
propose to "drop" the clause that the functional performance criteria also
include AT - why not just propose that the functional performance criteria
only apply when AT is not provided and the application or product shall be
operable without additional AT for users who are blind?
