Wayne, Your rant wasn't bad, in fact it was informative, though nothing new was said, but you said it well. The web is probably no longer what was originally envisioned, but the original vision was limited and didn't take into account either the mushrooming of bandwidth and technology, or the popularity that the web has gained. At some time in the years to come, the "original" concept of the web will go away and the "horseless carriage" as a toy of the privileged will be gone ... it's almost there already! Unlike most on this list, I am very much "up" on cognitive issues because the needs in this area, especially as they affect education, have been my career. Because of long-term friendships in the adult disability community, I have kept up with the issues and am part of this debate. I care very deeply about the part of the population who labor through life inspite of cognitive disabilities - they are friends and family a-many. I am proud of each one who conquers the financial and learning hurdles and climbs on board the Internet. I know that for each one, there was a different reason, a different hope, a different need that brought them to this table. I could bore this group to tears with specific stories of how things came to be. But I cannot say that any one of them came to the web expecting to cherish "documents" ... Should they be sent back to tv just because the originators of the web didn't envision they would be here? Perhaps purists can argue so, but these people are too real to me for those arguments to have much flavor. My concern with seeing the cognitive issues included in WAI is because the published purpose is to insure the web accommodates all people with disabilities. WAI says it promises accessibility to ALL, and, when they're not damning business, promise the buying power of ALL disabled persons ... therefore, if it's called "accessibility for disabilities", it can't ignore some disabilities just because they weren't originally expected to come onboard. On the gl list there is a member who is both personally disabled cogitively, but also works as a teacher to those with more severe cognitively disabled. It's likely that a complete "translation" from text to icons will sometime be technically possible, but these needs are the extreme. The middle stream need is to illustrate text. If this is expressed: Every web document would be illustrated to reach the widest audience. Saying that document must be illustrated is a long way from saying "if you have to put a graphic on your page do this ..." .... It should say: "Illustrate your page; do this for each illustration ..." Notice it doesn't say "decorate your page" ... Will there be "documents" that can't be illustrated? Sure! but is it because the content isn't worth the effort? I would hope that more commercial sites would look at the IKEA-usa.com site suggested to me this morining, and look at the "glitzy" directions to put together a bookcase ... add the needed sound, and add a printable version, and a basic text version, for every item sold with directions, and leave it there so the customer could find it every time they needed it (instead of cluttering up a drawer full of directions and schematics ...) but this is much more than asking for mark-up language ... yet it seems to be in the same spirit, at least to me ...
