I'd like to make one more "promotional" comment: When I have read WCAG 2.0 drafts over the past year, I have noted a struggle to include requirements such this one in the 11 March 2004 draft [1]: "The following can be derived programmatically (for example, through a markup or data model) from the content without requiring user interpretation of presentation. ... hierarchical relationships such as paragraphs and lists... emphasis on specific words..." There are tons of format specifications out there. They don't all include markup for emphasis or lists, nor should they. I don't believe it will help authors to say "Use emphasis" if they are using a format specification that does not include markup for emphasis! Hence, the proposal suggests that WCAG 2.0 say the following: a) Authors should use accessible format specifications and use them as follows to create accessible content. b) To make an accessible format specification, do the following: i) If it includes audio, do the following.. ii) If it includes video, do the following.. iii) If it's a basic document language, use something in the HTML family. And do forth. Of course, authors will not be able to influence very often the design of "accessible formats"; this is why I think XAG is so important and why I would like to see it get done as quickly. Why do I think this model will speed up work? I think it's much easier to start with a statement like "Assume the author is using a format that supports accessibility" and to work from there. The first requirement that comes to mind is "Authors must use the accessibility features of the format; see part two of this document where those are discussed." Then, the rest of "Part One" of WCAG can focus on HOW authors use those features to create accessible content, e.g., by building clear navigation, by using simple language, etc. Thanks for reading the proposal, _ Ian [1] http://www.w3.org/TR/2004/WD-WCAG20-20040311/#content-structure-separation -- Ian Jacobs (ij@w3.org) http://www.w3.org/People/Jacobs Tel: +1 718 260-9447
