W3C announced the publication of WAI-ARIA 1.0 as a W3C Candidate Recommendation on 18th January 2011. A Candidate Recommendation (CR) is a major step in the W3C standards development process which signals that there is broad consensus in the Working Group and among public reviewers on the technical content of proposed recommendation. The primary purpose of the CR stage is to implement and test WAI-ARIA. If you are interested in helping or have additional comments you are invited to follow the content submission instructions.
It does occur to me that in light of the significant development work we are seeing in areas such as repositories, e-learning systems, e-research, etc. there may be examples of developments which have enhanced the user interface in ways which enhance access for users with disabilities. If you have made use of WAI-ARIA 1.0 techniques in the development of your services, as mentioned on the W3C blog, W3C WAI would welcome such feedback. Please note that the closing date for comments is 25th February 2011.
