Kynn, Thank you for investing the time and effort needed to write up a proposal. This provides the material necessary to allow the working group to consider the merits of the "policy framework" analysis. There was much discussion of the relationship between WCAG and policy at last week's face to face meeting. It was also made quite clear at the interest group meeting, by developers themselves, that they need clear guidance regarding how to formulate an implementation plan and how to determine the order and priority with which to address various checkpoints. It was also argued that organizations should be provided with some flexibility in defining policies, but that entities with fewer resources would benefit significantly from a limited range of pre-defined policy options' being laid down in advance. There was also disagreement over whether the working group should, or should not, prioritize the checkpoints of the 2.0 guidelines. Opposition to the establishment of priorities arose from two distinct but complementary arguments. First, as noted above, it was asserted that policy makers, whether at a governmental or organisational level, would inevitably determine priorities based on a variety of pragmatic considerations, which depend on context and circumstances that the WCAG working group is in no position to foresee or take into account. At an organisational level, for example, implementation priorities will be determined by a variety of factors, including the authoring tools and implementation technologies in use, whether the content is being created anew or "retrofitted", etc. Given the perceived inevitability of policy setting, it was argued that the guidelines should support these efforts by providing some flexibility, but without allowing unconstrained subsetting or modification of the requirements. It was correspondingly argued from a user's point of view that any prioritization within the guidelines would necessarily be discriminatory, since almost every checkpoint represents an absolute barrier to accessibility for some identifiable group, and by establishing priorities, the working group would not only be legitimising, but also engaging in the practice of determining whose access needs should be treated as of foremost importance, and whose, by contrast, carry less weight. It was recognised that policy setters will inevitably make such decisions, but these, it was suggested, should be required to be transparent as to whose needs will and will not be satisfied by any particular policy formulation. Metadata was favoured as the preferred mechanism through which to match users' needs with the policy implemented by a particular site. An analysis of the interdependencies among the checkpoints of the 2.0 draft indicated that most could be implemented independently of one another, but that the benefits of some checkpoints could not be realised unless certain other checkpoints were regarded as prerequisites. It was acknowledged that any implementation and conformance framework provided by WCAG must take cognisance of these interdependencies, as well as the more specific dependencies arising at a technology-specific level. My impression of the meeting is that proponents of priorities were willing to consider alternative proposals that did not involve the prioritisation of checkpoints as in WCAG 1.0. The underlying concern was that content developers be provided with firm policy guidance, and there were suggestions that this could be achieved by offering a well-defined framework for decision making, including one or more sample policies. Some participants were also concerned to ensure that the prioritization and policy-setting process carried out by organisations would not be completely open-ended, so that content which was tailored for access by a specific group defined according to disability, could not be regarded as conforming to the guidelines. The upshot of these deliberations appears to be that the guidelines should impose constraints upon, and offer guidance in, the formulation of policies, whether by governments, organisations or individual developers. It was agreed that there should be clear and explicit "success criteria" with which to determine whether web content conforms to each checkpoint. There was no consensus as to whether the guidelines should have an over-arching conformance scheme requiring anything more than that developers be able to assert (via metadata or otherwise) which checkpoints they claim to have implemented. A possible solution not discussed at the meeting would be to regard web content as conforming to the guidelines if it satisfies those requirements defined in a policy that accords with the framework provided by WCAG. This would be broadly consistent with Kynn's proposal and generally reflective of the ideas arising from the face to face meeting. It should be pointed out that I am not necessarily advocating this idea, but merely raising it as a possibility which accords with the arguments reported above. Full details of last week's deliberations will appear in the minutes of the meeting, which will be published as soon as Wendy, Charles and Cynthia have compiled their notes and made them available on the web site.
