- An `img` with an `alt` attribute whose value is the empty string is mapped to the
-
`presentation` role. It has no accessible name.
+ 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, the
video element
MAY be exposed 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> <!-- computedrole returns 'html-video' --> <main role="html-video"> <!-- Author error. computed role returns 'main' -->
-
Otherwise, if there is no `alt` attribute use the `title` attribute.
-
Otherwise there is no accessible name.
-

-
- Text-level Element Accessible Name Computation
-
- `abbr`, `b`, `bdi`, `bdo`, `br`, `cite`, `code`, `dfn`, `em`, `i`, `kbd`, `mark`, `q`, `rp`, `rt`, `ruby`, `s`, `samp`, `small`, `strong`, `sub` and `sup`, `time`, `u`, `var`, `wbr`
-
-
-
- If the element has an `aria-label` or an `aria-labelledby` attribute the accessible name is to be calculated using the algorithm defined in Accessible Name and Description: Computation and API Mappings.
+ 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.
+
+
- - Otherwise use the `title` attribute.
-
- If none of the above yield a usable text string there is no accessible name.
+ AXAPI:
+
+ - User agents should return a user-presentable, localized string value for the Mac Accessibility AXRoleDescription.
+
-
-
-
-
- Accessible Description Computation
-
- An accessible description MAY be provided to any HTML element that is a valid child of
- the `body` element. The following list represents the order of precedence for user agents to compute the
- accessible description of an element. As defined by
- Accessible Name and Description Computation: Description Computation ,
- user agents MUST use the first applicable description source, even if its use results in an empty description.
-
-
- -
- If the element has an `aria-describedby` or
- `aria-description` attribute refer to the computation conditions defined in
- Accessible Name and Description: Computation and API Mappings.
-
- -
- Otherwise, if the accessible description is still empty, and the element is:
-
- -
- a `table` element which has a child `caption` element, use the
- text equivalent computation of the subtree of the first `caption` element if it
- was not used as the accessible name.
-
- -
- a `summary` element, use the text equivalent computation of its subtree if it was not
- used as the accessible name.
-
- -
- an `input` element whose `type` attribute is the `button`, `submit` or `reset` state, and it has a `value` attribute, then use the flat string
- of the attribute if it was not used as the accessible name.
-
-
-
- -
- Otherwise, use the flat string of the `title` attribute if it was not used as the accessible name for the element.
-
- -
- If none of the above are applicable, there is no accessible description.
-
-
-
-
-
-
-
- Privacy considerations
-
- In accordance with Web Platform Design Principles, this specification provides no programmatic
- interface to determine if information is being used by Assistive Technologies. However, this specification does allow an author to present different information to users of Assistive
- Technologies from the information available to users who do not use Assistive Technologies. This is possible using many features of the ARIA and CORE-AAM specifications, just as this is
- possible using many other parts of the web technology stack. This content disparity could be abused to perform
- active fingerprinting of users of Assistive Technologies.
-
-
-
- Security considerations
- This specification introduces no new security considerations.

+ 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.
+
Note
+ 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.

+ If the element includes both the required attribute and the aria-required attribute with a valid value, User Agents MUST expose only the required attribute value.
+
+ 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").

+
+
+ 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.

+ 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.
+
+ Note
+ User Agents notify assistive technology when relevant accessibility information changes, sometimes by destroying and recreating the accessibility object, or sometimes by notifying of changes
+ to the object per the specified
+ name change event mappings and description change event mappings.
+
+ -
+ If the first
summary element, which is a direct child of the details element, has an aria-label or an
+ aria-labelledby attribute the accessible name is to be calculated using the
+ algorithm defined in Accessible Name and Description: Computation and API Mappings.
+
+ - Otherwise use
summary element subtree.
+ - Otherwise use
title attribute.
+ - If there is no
summary element as a direct child of the details element, the user agent should provide one with a subtree containing a localized string of the word "details".
+ -
+ If there is a
summary element as a direct child of the details element, but none of the above yield a usable text string, there is no
+ accessible name.

+ In accordance with Web Platform Design Principles, this specification provides no programmatic
+ interface to determine if information is being used by Assistive Technologies. However, this specification does allow an author to present different information to users of Assistive
+ Technologies from the information available to users who do not use Assistive Technologies. This is possible using many features of the ARIA and CORE-AAM specifications, just as this is
+ possible using many other parts of the web technology stack. This content disparity could be abused to perform
+ active fingerprinting of users of Assistive Technologies.
+
+
+
+
+ This specification introduces no new security considerations.
