Corresponding policy for OpenACS is currently being written and will be published soon.
The conformance level to be satisfied is explained in the "Accessibility Conformance Level" section of the .LRN Accessibility Policy.
The "Accessibility page" refered by the .LRN Accessibility Policy states the conformance level and its domain of aplication for each version of the software.
Web Content Accessibility Guidelines
Note: Although automatic tools, such as TAW and "Cynthia says", may be useful to help the developer/author in addressing accessibility issues by providing informative reports, they can not certify the accessibility level of a page since many things need a manual review. Also, those tools won't be able to check a page protected by user and password (they would report on the login page, the one they can actually reach).
