Guideline A.1.2: (For the authoring tool user interface) Ensure that non-web-based functionality is accessible. [Implementing A.1.2] http://www.w3.org/TR/2015/NOTE-IMPLEMENTING-ATAG20-20150924/#gl_a12 Rationale: When authoring tools (or parts of authoring tools) are non-web-based, following existing platform accessibility guidelines and implementing communication with platform accessibility services facilitates access by all authors, including those using assistive technologies. A.1.2.1 Accessibility Guidelines: If the authoring tool contains non-web-based user interfaces, then those non-web-based user interfaces follow user interface accessibility guidelines for the platform. (Level A) Note: The (optional) explanation of conformance claim results (https://www.w3.org/TR/ATAG20/#conf-explanation-results) should record the user interface accessibility guidelines that were followed. Implementing A.1.2.1 A.1.2.2 Platform Accessibility Services: If the authoring tool contains non-web-based user interfaces, then those non-web-based user interfaces expose accessibility information through platform accessibility services. (Level A) Note: The (optional) explanation of conformance claim results (https://www.w3.org/TR/ATAG20/#conf-explanation-results) should record the platform accessibility service(s) that were implemented.
