Another place that I think we get ourselves into trouble is that we say that P1 P2 and P3 are based entirely on the degree of access they provide and not at all on ease of implementation. HOWEVER, we do in fact filter our recommendations on practicality. We do not list everything that would be helpful or even needed if we do not feel that it would be doable or rational to ask for. Some of the problem we run into with the cognitive area is that we try to act like there are clear lines - and then force reality to fit these lines. This leaves people in the cognitive area thinking that we are talking out of both sides of our mouth --- or saying that P1 has a clear “bright line” definition when they can see that it doesn't when we are talking about cognitive. What they may not see is that is doesn't when we are talking about other disabilities as well. Also, it NEVER CAN when it comes to cognitive, since everything would need to be a P1. That is, there will be some groups of people with cognitive that will never be able to use a web page even if you did everything to it. Thus everything would be required for that last person (or group) who could use it (if you did everything) to use it. Also, it should be noted that there are some types of information on the web that we can never really make accessible to people who are blind - and some types that we can never make accessible to people who are deaf .) So - where does that leave us. Hmmmmmmmmm I guess we might need to admit that these are not absolute pure guidelines… and that they are limited to “what is reasonable to require of most all web pages/sites”. That is, the guidelines are not designed to make all pages accessible to all users. Rather, they are what is reasonable to require of most all pages/sites. This will make our discussions more honest but perhaps more difficult as well. Thoughts?? Gregg -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Human Factors Dept of Ind.
