In regards to your comment about recommending obsolete solutions. This is not what I'm advocating. I am advocating creating a database of individual guidelines marked with extra information regarding the browsers and assistive technologies for which they are relevant. These guidelines can then be compiled by a simple program into a different collections that suit our varying needs. One compilation could be what we we now consider the WAI authoring working draft, but another collection would be the WAI working draft plus those guidelines that are necessary for making pages accessible on current versions of IE 4.0, Netscape 4.0, and the major screen readers. Such an approach provides a definitive notion of accessibility that takes into account the past, present, and future of the guidelines while denying the idea of a single measure of accessibility.
