Elements must only use allowed ARIA attributes.
The first claim in the WAI-ARIA Authoring Practices 1.1 document, immediately after the introduction, says "No ARIA is better than Bad ARIA", and it explains: "Incorrect ARIA misrepresents visual experiences, with potentially devastating effects on their corresponding non-visual experiences". The ARIA spec explicitly defines a list of roles, states, and properties. Some require to be part of a larger structure, others require specific additional attributes, or their state should be programmatically managed. Make sure you use only valid ARIA attributes and that all their additional requirements, if any, are satisfied.
