La primera regla de ARIA

Conviene recordar la primera regla de WAI-ARIA (2.1 First Rule of ARIA Use):
If you can use a native HTML element [HTML51] or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so. 
Under what circumstances may this not be possible?
  • If the feature is available in HTML [HTML51] but it is not implemented or it is implemented, but accessibility support is not.
  • If the visual design constraints rule out the use of a particular native element, because the element cannot be styled as required.
  • If the feature is not currently available in HTML.
