A clip that was buried in a long email on closed system list. Pulled out
here for thought.





Non-Closed System Approach.

One way to approach this is to omit the topic of 'closed" and simply say
that products must be accessible or must meet the 508 access standards, and
that this can be established by showing that the product is accessible (or
meets the standards) either without AT or with any AT that it can be
established that users will reliably have with them and will reliably be
permitted to use when they encounter the product.



Then we don't have to worry about open or closed (which are very problematic
definitions). We also don t have to worry about products that are
theoretically accessible but no AT exists or users won't have it.



We also don't have to worry about gray areas. There will still be gray
areas (always are) but it will be in very direct concrete terms. (e.g. is
there AT available or will users have it or be able to use it).
