Referencing W3C Accessibility Guidelines
6th March 2009 by Liam McGee
Now that WCAG2.0 is out there and being used day-to-day, time to update all your links.
To refer to and link to the latest completed version that is the recommended Web Standard, do not include a number, for example:
Authoring Tool Accessibility Guidelines (ATAG) http://www.w3.org/TR/ATAG/
User Agent Accessibility Guidelines (UAAG) http://www.w3.org/TR/UAAG/
Web Content Accessibility Guidelines (WCAG) http://www.w3.org/TR/WCAG/
Accessible Rich Internet Applications (WAI-ARIA): http://www.w3.org/TR/wai-aria/
Only include the numbering (e.g. http://www.w3.org/TR/WCAG20/) if you need to link to a specific version, and not to superseding versions.
Most references to WCAG should link readers through to the WCAG overview, rather than dumping straight into the technical specification. The overview is at www.w3.org/WAI/intro/wcag
