Appendix D The differences between WCAG 1.0 and WCAG 2.0 (Non-Normative)

Since the release of WCAG 1.0 in May 1999, the WCAG Working Group has received feedback on priorities of checkpoints, the usability of the set of documents, and requests for clarifications on the meaning of specific checkpoints and what is needed to satisfy them. Thus, it is intended that WCAG 2.0, when it eventually becomes a W3C Recommendation:

D.1 Improvements in WCAG 2.0

We hope that WCAG 2.0 will have several improvements over WCAG 1.0. While the primary goal of WCAG 2.0 is the same as WCAG 1.0 (to promote accessibility of Web content) additional goals for WCAG 2.0 include improvements that will:

  1. Ensure that requirements may be applied across technologies

  2. Ensure that the conformance requirements are clear

  3. Ensure that the deliverables are easy to use

  4. Write to a more diverse audience

  5. Clearly identify who benefits from accessible content

  6. Ensure that the revision is "backward compatible" with WCAG 1.0
