Accessible names for object elements (object-accessible-name)

Object elements that render non-text content must have non-empty accessible names. This can be provided using the title attribute, aria-label, aria-labelledby, or fallback content.

Note: The aria-labelledby attribute must reference an existing element with accessible text. If the referenced ID does not exist, the accessible name is not computed.

Object with missing label ID:

This <object> embeds an audio file and uses aria-labelledby="download" to define its label. However, there is no element with ID "download", so the object has no accessible name and fails WCAG 1.1.1.


Note: Possible to implement because broken aria-labelledby references and the absence of other accessible name sources can be detected programmatically.
