WAI-ARIA provides semantics designed to allow an author to properly convey user interface behaviors and structural information to assistive technologies in document-level markup. WAI-ARIA 1.1 adds features to WAI-ARIA 1.0 to complete the HTML+ARIA accessibility model.
The new and updated working draft is open for review as they are looking for comments. WAI-ARIA 1.1 adds:
- table roles and a model to distinguish tables from grids.
- the “aria-roledescription” property to refine user understanding of roles.
- changed applicability of “aria-readonly” and “aria-level”.
- expanded explanation of “supported” vs. “required” states and properties.
Core Accessibility API Mappings (Core-AAM) and Accessible Name and Descriptions: Computation and API Mappings (AccName-AAM) provide support for the new WAI-ARIA 1.1 features as well as more complete accessibility API Mapping for other features.
