Certain ARIA roles must be contained by particular parent
roles in order to perform the intended accessibility functions.
The Algorithm, in Simple Terms
Checks all elements that contain a WAI-ARIA role to ensure that all required parent roles are present
Why this is Important
For each role, WAI-ARIA explicitly defines which child and parent roles are allowable and/or required. ARIA
roles missing required parent
roles will not be able to perform the accessibility functions intended by the developer.
How to Fix the Problem
Ensure all ARIA roles are contained by their required parent element, if any.
