Scott, The guidelines promote Universal design, rather than targetted design, precisely in order to avoid the problem of helping one group at the expense of another. They recognise that there may be situations in which content is created in a way that is not generally accessible, and provide for that content to also be provided in a generally accessible format in order to claim conformance for that content. Note that this is not the same as a text-only version. For example, there are more people with partial vision than there are blind people in Australia by several times, and I presume that this is the case elsewhere. Most of these people find images useful to a certain extent (if they are properly used, which is a big if) and it is possible through good design to use graphics in a way which does not have anegative impact on blind users. Such universal design stretegies serve the various communities much better than a couple of groups being targetted (prehaps completely blind and completely deaf) and every other group being ignored. The guidelines make no distinction between dynamically and statically generated content because they describe requirements so that end-users can access content. If you can provide us with information about access problems that are not addressed by the curret guidelines, please do, so we can address them in revisions. That is why we seek a diverse group of members for the working group - no one person is likely to know all the problemfaced by all the users of the web.

Don't the guidelines themselves make certain generalizations about particular groups. For example, I can point out a number of areas of access problems that the guidelines don't address that cause trouble for users. These areas are not generally known because there has been very little research based on observation on what kinds of problems blind users can run into. By ignoring the problems, the guidelines are assuming they are not issues that affect users very much.
