Today the W3C published an update to the Techniques for WCAG 2.0 document and the Understanding WCAG 2.0 document. The Techniques document now includes techniques for Flash content and helps define a way for authors to comply with WCAG 2.0.

Like other sufficient techniques, the Flash techniques do not describe the only way to comply with WCAG 2.0 but define a collection of techniques that an author may choose to utilize. The table below provides a listing of the WCAG level A and AA success criteria and the Flash-specific and General techniques that authors can employ to meet the requirements of the success criteria.

As always, please send comments on existing techniques or suggestions for additional ones. This represents the first pass at the techniques for Flash, we’ll be working on adding more in the future.
