This is a Candidate Recommendation of Authoring Tool Accessibility Guidelines (ATAG) 2.0 from the Authoring Tool Accessibility Guidelines Working Group. This version integrates minor changes in response to comments received on the 10 April 2012 Last Call Working Draft. The Working Group received 33 comments on this draft. Most of the changes were deemed non-substantive, providing clarification and improving the ability to test the success criteria. One success criterion A.4.1.3 Content Changes Reversible (Enhanced)) was removed. For complete detail of the changes, see the automated difference document of ATAG 2.0 with all changes marked from the Last Call Working Draft.
A Candidate Recommendation is a document that has been widely reviewed and is ready for implementation. Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. Before the specification can progress to Proposed Recommendation, the CR exit criteria must be met. A test suite and an implementation report will be made during the Candidate Recommendation period.
Besides these implementations, feedback on implementation and use of this specification is welcome, including from implementations not selected as part of the formal implementation report for exiting Candidate Recommendation.
Working closely with authoring tool developers, we expect to receive initial implementations by @@ date @@ and to show evidence of meeting the exit criteria by @@ date @@
The Authoring Tool Accessibility Guidelines Working Group intends to submit this document for consideration as a W3C Proposed Recommendation as soon as the following conditions are met.
Note 1: "Independent authoring tools" are tools by different developers that do not share (or derive from) the same source code for the relevant feature(s). Sections of code that have no bearing on the implementation of this specification are exempt from this requirement. The authoring tools must be a shipping product or other publicly available version; or a non-shipping product release that has implemented the feature(s) for a period of at least one month in order to demonstrate stability. Experimental implementations specifically designed to pass the test suite and not intended for normal usage, are not permitted.
Note 2: "implemented" refers to situations in which a success criterion is applicable to a given authoring tool and the authoring tool meets the success criterion. This is in contrast to situations in which a success criterion is not applicable.
Note 3: For example, if the WCAG success criteria at level A are satisfied, then the ATAG success criteria is satisfied at level A. If the WCAG success criteria at level AA are satisfied, then the ATAG success criteria is satisfied at level AA. If the WCAG success criteria at level AAA are satisfied, then the ATAG success criteria is satisfied at level AAA.
As a part of the Candidate Recommendation process, any items that might change or where there may not be implementations are marked as "at risk." "At risk" in no way implies that these success criteria are less important to accessibility. It is a W3C requirement to identify any provision for which the Working Group believes it may not be able to document the required implementations by the end of the Candidate Recommendation period.
If at least two implementations of each of the following success criteria do not exist at the end of the Candidate Recommendation period, the success criteria may be modified as stated:
If at least two implementations of each of the following success criteria do not exist at the end of the Candidate Recommendation period, the success criteria may be removed.
