I think that this approach (having a link to a page which clearly does meet requirements, and having that link itself meet the requirements of WCAG) allows a page to conform to any level. I believe that is part of what Cynthia tried to make ore explicit in her proposal for a checkpoint on this topic. Some proposed explanatory information about the checkpoint (using the curent version): The alternative page must meet the requirements for a particular conformance level. A page that is just text may not meet the requirements of WCAG, nor the requirements of users. For example, for a user who has difficulty seeing content, audio content may still be very usful, and should not be stripped from the content presented to them. Likewise a user who is deaf may find video content extremely helpful in accessing the site, and should be able to use it. If a site has an alternative version available for a page or part of a page that does not meet the same conformance level as the rest of the site, and if the alternative version does meet the conformance level of the rest of the site, and if the means of finding the alternative version meets the conformance level of the rest of the site, then the site can conform to any level. Otherwise conformance for the site will be to the lowest conformance level for any single part of the site. The same principle can be applied to assesssing conformance of a page, which may have some components that are not themselves accessible (but note also the direct requirement for accessibility of components with a User Interface. CMN: How does this work in WCAG 2?) I think that is a bit waffly, but it should give the idea of how to use 11.4 in my humble opinion. cheers Charles McCN On Thu, 26 Oct 2000, Leonard R.

I'm not sure how WCAG 11.4 ("after best efforts, you cannot create an accessible page, provide a link to an alternative page ...") since since its condition is "accessible page" with no mention of priority. Also the guideline is itself priority 1... it's confusing to apply it to priority 2 requirements. If this isn't available as a general escape hatch, we need to build it into 3.1. Len There are some pages, e.g. http://www.rivertrout.com/main.html , that are fundamentally artistic,where CSS text would spoil At 03:17 PM 10/25/00 -0400, Wendy A Chisholm wrote: >Please: >review this entire message. > >Please: >Do not respond to this message unless you have new information that has >not been presented yet.
