W3C WAI today published updates to two supporting documents for Web 
Content Accessibility Guideline (WCAG) 2.0:
- Techniques for WCAG 2.0 http://www.w3.org/TR/WCAG20-TECHS/
- Understanding WCAG 2.0 http://www.w3.org/TR/UNDERSTANDING-WCAG20/


WCAG 2.0 itself is a stable document that does not change. The WCAG 
guidelines and success criteria are designed to be broadly applicable to 
current and future web technologies, including dynamic applications, 
mobile, digital television, etc. For an introduction to the WCAG 
documents, see the WCAG Overview <http://www.w3.org/WAI/intro/wcag.php>.

The supporting resources published today (called W3C Working Group 
Notes) provide specific guidance -- including code examples, resources, 
and tests -- and are updated periodically to cover current practices for 
meeting WCAG.

Important updates:

Some of the updates published today provide important clarifications on 
the role of techniques. The *new Understanding Techniques for WCAG 
Success Criteria* section 
explains that W3C's techniques are informative and are not intended to 
be required. It reiterates that the basis for determining conformance to 
WCAG 2.0 is the success criteria from the WCAG 2.0 standard (not the 
techniques). It points to cautions against requiring the only W3C's 
published techniques under "What would be the negative consequences of 
allowing only W3C's published techniques to be used for conformance to 
WCAG 2.0?" in the WCAG 2 FAQ 

The updates include clarifications in existing techniques for different 
technologies. Note that publication of techniques for a specific 
technology does not imply that the technology can be used in all cases 
to create accessible content that meets WCAG 2.0. Developers need to be 
aware of the limitations of specific technologies and ensure that they 
provide content in a way that is accessible to all their potential users.

Some of the updates clarify how WCAG can apply in different situations 
and they help set the foundation for future work on techniques for 
HTML5, WAI-ARIA <http://www.w3.org/WAI/intro/aria>, and mobile 
accessibility <http://www.w3.org/WAI/mobile/>.

Will you help?
Updating and expanding these WCAG supporting documents is on-going work.
- You can send in your ideas for new techniques via the Techniques for 
WCAG 2.0 submission form at <http://www.w3.org/WAI/GL/WCAG20/TECHS-SUBMIT/>.
- If you are interested in actively contributing to the development of 
additional WCAG support material through the WCAG Working Group, please 
see Participating in WAI at <http://www.w3.org/WAI/participation> and 
contact Michael Cooper.
