| Techniques |
- Container elements using
aria-owns attribute must accurately reference the associated child elements.
- A child element can only be referenced by one container element using the
aria-owns attribute.
- Update the application to use the DOM parent/child relationships instead of using
aria-owns technique.
- NOTE: HTML DOM parent/child relationships for defining relationships is preferred over the use of
aria-owns attribute, since it is less likely to result in authoring errors associated with creating and referencing elements with unique ids.
