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-1.2]]] 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]].

User Agents MUST expose HTML elements or attributes with default WAI-ARIA semantics 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]].

Exposing HTML Features That Require a Minimum Role

A minimum role is the equivalent WAI-ARIA role an element will map to if the element does not have a more specific implicit role or platform role mappings, e.g., a non-generic role. This can help ensure that users of assistive technologies get the best possible experience for commonly-used and valid HTML markup where otherwise a role would not be exposed.

A minimum role is provided when all of the following conditions are true:

the author has not specified a valid explicit WAI-ARIA role to the element, or the specified role is either `none`, `presentation`, or `generic`;
the element either has no implicit WAI-ARIA role or platform role mappings, or it has an implicit `generic` or `none` computed role;
and the author has specified attributes which require a minimum role mapping for the element.

The HTML Attribute State and Property Mappings section identifies the specific global attributes which would require an element map to a minimum role.

When these conditions are met, user agents MUST expose an object using the mappings defined in CORE-AAM for the specified minimum role. If the element has multiple attributes specified which require a minimum role be returned as the computed role for the element, prioritize the more specific role in the ARIA taxonomy.

HTML Element Role Mappings

User agents MUST map HTML elements with implicit WAI-ARIA role semantics to platform accessibility APIs according to the identified WAI-ARIA role mapping as defined in the [[core-aam-1.2]] specification.
"Not mapped" 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. However, authors can force some of these elements to be rendered. For instance, by overriding user agent styles to render elements that would have been otherwise set to `display: none`. In these cases, the user agent SHOULD map such elements to the role of `generic`, unless other HTML features have been specified which would require a more specific minimum role to be exposed.
Where an element is indicated as having "No corresponding (WAI-ARIA) role", or is mapped to the `generic` 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 which [[WAI-ARIA-1.2]] does not prohibit the use of `aria-roledescription`.
Some HTML elements expose implicit WAI-ARIA roles depending on whether they have been provided an accessible name. 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 of this document.

Platform API mapping requirements

When HTML elements do not have an exact or equivalent mapping to a valid, non-abstract WAI-ARIA role, a unique `computedrole` string has been specified to serve as the return value for interoperability testing purposes. For instance, user agents MAY expose the `video` element with a `computedrole` of "`html-video`". Authors MUST NOT use any `html-`prefixed computed role string in the role attribute (such as `html-video`). User Agents MUST ignore any abstract or invalid role token.
<video>  <main role="html-video"> 
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.

[[wai-aria-1.2]]	`table` role
Computed Role	To compute the role given table element `element`: If element is in not being rendered, return `table`. Tables which are not rendered are unlikely to be used for layout, but could be present to supplement otherwise inaccessible graphics. Firefox Chrome WebKit does not include this heuristic. If element is editable, return `table`. Tables which are in an editable state need to act as data tables to allow for rich text editors to create and edit tables which otherwise might have insufficient rows or columns to be considered a table. Firefox Chrome WebKit If element has a `datatable` attribute whose value is `"0"`, return `table` This is a nonstandard attribute used to force tables to be as such.

HTML Attribute State and Property Mappings

User agents MUST map HTML attributes with default WAI-ARIA state and property semantics to platform accessibility APIs according to the identified WAI-ARIA state and property mapping 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.
User interaction with certain HTML elements will set an element's dirty value flag. These elements, as identified in [HTML], could have attributes that represent the default value or state of the element. When the dirty flag is set, that default value or state does not necessarily determine the value or state of the element or corresponding accessible node.

Comments	Note: the `aria-autocomplete` attribute and the HTML `autocomplete` attribute have disparate features. The `aria-autocomplete` attribute is not supported on the HTML `form` element or elements with an explicit ARIA `form` role. When used on a `form` element, the `autocomplete` attribute identifies whether form controls owned by the form will have their autofill field name set to "`on`" or "`off`" by default. See `autocomplete` for `input`, `select`, `textarea` for control mappings.

`open`

HTML Specification	`open`
Element(s)	`dialog`
[[WAI-ARIA-1.2]]	If the `open` attribute is set via the `showModal()` method then `aria-modal="true"` and `aria-hidden="false"`. Otherwise, if the `open` attribute is set via the `show()` method, or explicitly specified by an author, then `aria-modal="false"` and `aria-hidden="false"`.
MSAA + IAccessible2	Use WAI-ARIA mapping
UIA	Use WAI-ARIA mapping
[[ATK]]	Use WAI-ARIA mapping
AX	Use WAI-ARIA mapping
Comments	The `open` attribute's value is irrelevant. When the `open` attribute is not specified the default user agent styling for a `dialog` is `display: none`. Authors can reveal a `dialog` through the style layer by modifying its `display` property. If revealed this way then the `dialog` is `aria-modal="false"` and `aria-hidden="false"`.

MSAA + IAccessible2	Relations: `IA2_RELATION_DETAILS_FOR` points to invoking element. See Comments. Object attributes: `ispopup: <value>` where `<value>` reflects the popover type.
UIA	A details relation is made with the invoking element, if an invoking element exists which meets the conditions for necessitating a details relationship. See Comments.
[[ATK]]	Relations: `RELATION_DETAILS_FOR` points to invoking element. See Comments. Object attributes: `ispopup: <value>` where `<value>` reflects the popover type.
AX	TBD
Comments	User agents MUST NOT expose a details relation between a `popover` and its invoking element under the following conditions: when the `popover` is the next immediate accessibility sibling to the invoking element, when the element has a `popovertargetaction=hide` attribute value, or when the element is a descendant of the `popover` and its `popovertarget` is the "`auto`" state. If specified on an element with an implicit role of `generic`, then the element's role instead maps to `group` for all `popover` states. There are no unique mappings for the different `popover` states. Any accessibility mapping changes for the popover element would be the responsibility of the author. e.g., using different base HTML elements, attributes, or ARIA attributes to make such changes.

`popovertarget`

HTML Specification	`popovertarget`
Element(s)	`button`; `input type=button, image, reset, submit`
[[WAI-ARIA-1.2]]	If the associated element is displayed as a popover: `aria-expanded=true` If the associated element is hidden: `aria-expanded=false` If the associated element is an accessibility ancestor of the element with the `command` attribute or is not present in the DOM: `aria-expanded=undefined` If the associated element is not a valid `popover` element: no `aria-expanded` mapping.
MSAA + IAccessible2	Use WAI-ARIA mapping Object attributes: `details-roles:popover`
UIA	Use WAI-ARIA mapping
[[ATK]]	Use WAI-ARIA mapping Object attributes: `details-roles:popover`
AX	Use WAI-ARIA mapping
Comments	User Agents MUST expose an `aria-details` relation with the associated popover element except under the following conditions: The element's `popovertargetaction` attribute value is "`hide`" The associated popover element is the next immediate accessibility sibling to the invoking element, The element's implicit or explicit `popovertargetaction` is the "`auto`" state and the element is a descendant of the `popover` it is associated with. A button that represents a submit button with a [=button/form owner=] cannot invoke a popover.

If an element is required, user agents MUST NOT expose the element with an intitial invalid state (`aria-invalid="true"`). The user agent SHOULD expose the invalid state only after 1) a user has purposefully interacted with a required element, or attempted to submit a form and 2) the element, or elements, do not meet constraint validation. Until these conditions are met, user agents MUST expose the elements as (`aria-invalid="false"`).

Comments	Some platforms (IAccessible2, ATK, UIA) do not expose an accessible object for the list item marker, whether it was created and then pruned from the accessibility tree, or never created in the first place. 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.
