These are exactly the right issues to be raising, and they allow me to offer the extended treatment that I should have given yesterday, but which I omitted for the sake of brevity. First, note that tasks and language features correspond quite well, especially in formats that have numerous features, as is true of HTML. All of the tasks John mentions can be tied to specific language features or to the techniques that would be written anyway to cover the success criteria (e.g., those related to navigation and orientation). Having said this, there are several options that could be taken. 1. The task-oriented and reference sections could be two different orderings of the same material within each techniques document. This would constitute the least amount of work, I suspect. 2. The task-oriented section could be written as a tutorial for the application of the guidelines. This would require writing and maintaining it separately from the reference section, for each techniques document. 3. As another alternative, a single, task-oriented tutorial-style presentation, covering all of the available techniques documents, could be written. This way, the task-directed material would cover multiple technologies in an integrated fashion, instead of comprising a separate section of each techniques document. While I think a task-directed tutorial should be written, it is less clear whether this is the responsibility of the WCAG working group. Further, considerations of effort, time and resources will need to be weighed against the advantages of including such a deliverable within the ambit of WCAG techniques, focusing first and primarily on what is needed to bring the guidelines to Recommendation status. It is with these desiderata firmly in mind that I have included option 1 as the minimalist alternative.
