The way in which I have customarily conceived of the relationship is as follows: 1. There is a threshold requirement that any access strategy stipulated by the guidelines be technically possible, meaning that it can feasibly be implemented in accordance with current or developing standards and technologies. 2. The guidelines must be applicable to web sites in general, and not only to those which provide specific types of content or are intended for particular, identifiable audiences--in other words, the guidelines are framed in such a way that the developer of any web content should be able to apply them, though obviously, not every guideline or checkpoint is relevant in all circumstances. For instance, checkpoints related to images are relevant only where the content provider chooses to use graphics. 3. Once the threshold requirement has been satisfied (item 1, above), the priority is then assessed in terms of the three definitions set forth in the guidelines, which are founded exclusively on what may be called considerations of "impact". I agree with Gregg that in the cognitive case, this scheme runs into difficulties, for the reasons which he has so clearly enunciated: a combination of access strategies is needed, which may, or may not, work in relation to any particular individual (depending on the nature of his/her cognitive abilities, experiences, interests, etc.), and so it becomes more difficult to establish firm priority levels. Also, there are certain classes of content which are more difficult to make accessible to people with cognitive disabilities, then are others. I do not pretend to have all, or even any, of the solutions to this problem, which I would argue requires further consideration within the working group. One observation that should be emphasised, however, is that the notion of "impact" (or, on the positive side, the ameliorating value of an access strategy) is as close to a clear, objective criterion of priority as we have been able to come. In particular, it has the merit of largely avoiding policy considerations, by which I mean specifically the need, within any organisation, society, government, etc., to consider the practical, technical and ethical advantages of accessibility (which in the final analysis is a matter of human rights), to examine the costs (financial and otherwise) of implementing access solutions, and to make a judgment as to what should be required, how soon, with what process of progressive implementation, and so on. As I have argued on earlier occasions, these judgments are complex, and very sensitive to context and circumstance. This is why some anti-discrimination laws are formulated in very general terms, and why they include provisions related to "unjustifiable hardship" (or whatever the preferred terminology is in the jurisdiction in question). It is a virtue of this working group's activities that it avoids entering into such considerations, and this should continue to be the case, whatever else we choose to do in adapting and improving the priority system. Disclaimer: the foregoing are personal opinions only.
