HTML Accessibility API Mappings 1.0

HTML Accessibility API Mappings 1.0 es una nueva especificación que está desarrollando el W3C. Por ahora está en estado "Editor's Draft".

El resumen dice:

HTML Accessibility API Mappings (HTML-AAM) defines how user agents map HTML 5.1 [HTML51] elements and attributes to platform accessibility application programming interfaces (APIs). It leverages and extends the Core Accessibility API Mappings 1.1 [CORE-AAM] and the Accessible Name and Description: Computation and API Mappings 1.1 [ACCNAME-AAM] for use with the HTML 5.1 host language. Documenting these mappings promotes interoperable exposure of roles, states, properties, and events implemented by accessibility APIs and helps to ensure that this information appears in a manner consistent with author intent.
The HTML-AAM is part of the WAI-ARIA suite described in the WAI-ARIA Overview.

Por ejemplo, en la siguiente imagen podemos ver que la etiqueta aside se corresponde con el role complementary de WAI-ARIA, y la etiqueta body con el role document.
