I don't think we'd get 3 revisions in three years, although I must admit I'd like to believe we could do that. But I think a 2-year revision cycle is a reasonable aim. > it is incredibly expensive and time consuming for stakeholders to update > policy, legislation, and their web sites every year... Sure. But first, they are not required to do so. WCAG 2.0, and for that matter WCAG 1.0 are likely to be available as reference targets for years to come. And second, and to me more important, it is also expensive *not* to improve accessibility when we know how to do it. The model for WCAG (except sometimes for triple-A requirements, although I'd like to see that change back in a few short years) is that every checkpoint improves accessibility for people, and that they are designed so that they don't do it at the expense of someone else. WCAG doesn't set a minimum bar, it's a technical document explaining the requirements that we have worked out. So if we have worked out how to stop excluding some people from some of the Web, I think it is important to express that, as a latest version of the Recommendation. In general, stakeholders aren't bound to "shift their goalposts", updating policy, technology, practice, etc, because we learned more about how to make the web work better. In some places, WCAG (or some equivalent) is set as the requirements, and very rightly changes to those requirements can be made or not according local policy. In others, and notably Australian and subsequently British discrimination law works like this, the requirement is to do what is necessary to remove barriers. If we know there are things that can be done but don't explain them, we are holding back societies who are actively deciding to invest in ensuring the greatest possible participation, which it is our goal to facilitate with the necessary technical information. As a final point, while it is indeed expensive to change things, the bigger the change the more expensive it is. If we make incremental updates, rather than dropping the massive shift that was understanding the change from WCAG 1.0 to WCAG 2.0, I think we'll be moving at approximately the natural "average" rate of development in the industry. Which will considerably ease the cost of adapting. > if we're not ready to incorporate all the task force work then lets wait > to release the next version we are I strongly suspect there is enough that we don't know how to do to keep the task forces busy for a decade working with today's technology - which will of course be superseded by then. Meanwhile in a few years since WCAG 2.0 was more or less frozen, the explosion in the diversity of screen size and resolution means that I, who don't wear glasses when working, regularly have to use more than the WCAG-minimum 200% zoom in order to do my job. And the off-the-shelf tools I have all happily go beyond that 200%. Likewise, the requirement for keyboard operability isn't actually what makes me able to use a small phone, and yet the technology and techniques are out there as reasonably common, but not universal, knowledge in the industry. > Currently there is *no* model that says we will have one important 2.x > release that incorporates *all* the task force work.

That said, I don't believe we'll get to a situation in the next decade - any more than we have in the last - where we think we've really got everything nailed down and know it all. As the Web develops, we constantly need to work on new things, and on improving the things that we sort of fixed already, as we learn more about the gaps and how to do better. cheers Chaals -- Charles McCathie Nevile - web standards - CTO Office, Yandex chaals@yandex-team.ru - - - Find more at http://yandex.com
