Summary of action items and resolutions: Wendy: to prepare a revised draft of the Charter for next week's meeting, incorporating comments from today's teleconference and clarifying the relationship with the W3C's Quality Assurance activity. Resolved: to discuss the Charter at next week's meeting with the intention of thereafter submitting it for consideration by the W3C. Gregg: to post revised definitions of the proposed conformance levels, integrating comments from today's discussion. Note: this action item has been completed (http://lists.w3.org/Archives/Public/w3c-wai-gl/2003AprJun/0035.html). During the meeting, the concept of a conformance level was clarified amid a discussion of whether the definitions should be treated as grouping requirements according to categories, or levels. It was emphasized that developers might legitimately implement all of level/category 1, then parts of level/category 3 in order to design specialised content to serve the needs of specific audiences. It was recognized that confusion had resulted from the identification level 1 with the notion of compatibility with assistive technologies, which is not the central or distinguishing concept underlying the definition. For clarification of this point and more precise wording, see the revised definitions posted by Gregg. There remains the question of whether, with these clarifications in place, the proposed definitions might serve to limit the accessibility of content conforming to the proposed minimum level, by users who don't interact with the Web via assistive technologies. Two solutions to this potential shortcoming were proposed: (1) transcoding technologies, demonstrated powerfully by Lisa's ongoing work in applying this technology to the implementation of Web Accessibility guidelines, notably WCAG (http://lists.w3.org/Archives/Public/w3c-wai-gl/2003AprJun/0034.html) (2) Recognition that "level 1" strategies provide interoperability with widely available user agents and other software, not just assistive technologies; It was also recognized that issues of conformance need to be examined in light of the allocation of requirements among the three proposed levels, and that a full restructuring proposal in accord with the suggested definitions remains to be written. The concern was also reiterated that if, at a minimum level, WCAG were to impose substantive constraints on authorial expression and presentational style, this would preclude, or at least severely limit, the broad adoption and implementation of the guidelines. It was further remarked that what can be made "invisible" in author-supplied presentations depends on the technologies which are being employed, and this needs to be taken into account. As not all semantic annotations that may be associated with Web content can reasonably be supplied by all developers, it was suggested that an element of reasonableness ought to be included in the definition of the minimum level. On the other hand, WCAG requirements serve as the basis for the development of authoring tools and other software, and, it was argued, should thus not be restricted to recommending practices that are supported by currently available authoring environments. The exact details of the conformance scheme were not discussed, nor was the task of actually working out the details of the proposal with respect to guidelines, checkpoints and success criteria.
