HTML Accessibility API Mappings 1.0

HTML Accessibility API Mappings (HTML-AAM) defines how user agents map HTML [[HTML]] elements and attributes to platform accessibility application programming interfaces (APIs). It leverages and extends the [[[core-aam-1.2]]] and the [[[accname-aam-1.1]]] for use with the HTML 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.

Mapping HTML to Accessibility APIs

General Rules for Exposing WAI-ARIA Semantics

WAI-ARIA support was first introduced to HTML in [[HTML5]].

Where an HTML element or attribute has default WAI-ARIA semantics, it MUST be exposed to the platform accessibility APIs in a way that conforms to General rules for exposing WAI-ARIA semantics in the [[[core-aam-1.2]]].

Conflicts Between Native Markup Semantics and WAI-ARIA

Where the host language is [[HTML]], user agents MUST conform to Conflicts between native markup semantics and WAI-ARIA in the [[[core-aam-1.2]]].

Exposing HTML Features That Do Not Directly Map to Accessibility APIs

HTML can include features that are not supported by accessibility APIs at the time of publication. There is not a one to one relationship between all features and platform accessibility APIs. When HTML roles, states and properties do not directly map to an accessibility API, and there is a method in the API to expose a text string, user agents MUST expose the undefined role, states and properties via that method.

For HTML elements or attributes with default WAI-ARIA semantics, user agents MUST conform to Exposing attributes that do not directly map to accessibility API properties in the [[core-aam-1.2]].

HTML Element Role Mappings

Notes:

HTML elements with default WAI-ARIA role semantics MUST be mapped to platform accessibility APIs according to those WAI-ARIA roles' mappings as defined in the [[core-aam-1.2]] specification.
A '?' in a cell indicates the data has yet to be provided.
"Not mapped" (Not Applicable) means the element does not need to be exposed via an accessibility API. This is usually because the element is not displayed as part of the user interface.
Where applicable, how an element participates in the computation of its own or another element's accessible name and/or accessible description is described in the Accessible Name and Description Computation section below.
Where an element is indicated as having "No corresponding [WAI-ARIA] role", user agents MUST NOT expose the aria-roledescription property value in the accessibility tree unless the element has an explicit, conforming `role` attribute value.
IAccessible2:
- All elements with accessible objects should implement the IAccessible, IAccessible2 and IAccessible2_2 interfaces.
UIA:
- When a labelable element is referenced by a `label` element's `for` attribute, or a descendant of a `label` element, the labelable element's UIA `LabeledBy` property points to the UIA element for the `label` element.
- Elements mapped to the `Text` Control Type are not generally represented as accessible objects in the accessibility tree, but are just part of the `Text` Control Pattern implemented for the whole HTML document. However, if they have any `aria-` attributes or an explicit `tabindex` specified, elements mapped to the `Text` Control Type will be represented as accessible objects in the accessibility tree.
AXAPI:
- User agents should return a user-presentable, localized string value for the Mac Accessibility AXRoleDescription.

HTML Attribute State and Property Mappings

Notes:

HTML attributes with default WAI-ARIA state and property semantics MUST be mapped to platform accessibility APIs according to those WAI-ARIA state and property mappings as defined in the [[core-aam-1.2]] specification.
A '?' in a cell indicates the data has yet to be provided.
"Not mapped" (Not Applicable) means the attribute does not need to be exposed via an accessibility API. This is usually because the attribute is not displayed as part of the user interface.
In some cases, while not directly exposed to accessibility APIs, an attribute can still impact the accessibility of an element. e.g. `autoplay` will automatically start playing `video` or `audio` elements.
All elements having an accessible object in IAccessible2 mapping are supposed to implement IAccessible, IAccessible2 and IAccessible2_2 interfaces.

Control Pattern: `Text`	Defines the list item marker, which has no accessible object, but is exposed as content in the accessible text of the associated list item.

Instead, they expose the list item marker as part of the associated list item's accessible text. In these cases, implementors need to consider such things as adjusting the offsets (e.g. for caret-moved events, text-selection events, etc.) for the updated list item text that now also contains the list item marker as content, rather than just taking the offsets unmodified from the list item renderer.

Accessible Name and Description Computation

The terms accessible name and accessible description are properties provided in all accessibility APIs. The name of the properties may differ across APIs but they serve the same function: as a container for a short (name) or longer (description) string of text.

The text alternative computation is used to generate both the accessible name and accessible description. There are different rules provided for several different types of elements, nodes, and combinations of markup.
