Microsoft has clarified the position on SharePoint 2010 Accessibility, those of us who have worked with public facing internet services will at some point have been told ‘SharePoint is not accessible’ and then been asked to add third party plug-ins or make serious customisation will appreciate some of the efforts Microsoft has made in this space.
WCAG 2.0 Compliance
SharePoint adopted the Web Content Accessibility Guidelines 2.0, WCAG 2.0, and set a goal for Level AA. Becoming a W3C recommendation on December 11th, 2008, WCAG 2.0 defines the expectations of and the techniques deployed in well-built, accessible Web sites. The SharePoint teams followed the spec’s developments, and we designed and tested SharePoint 2010 against the guidelines. WCAG 2.0 represents a modern, international standard that’s as valuable to developers as it is to Web users.
