An element whose implicit native role semantics will not be mapped to the accessibility API.

A message with important, and usually time-sensitive, information.
<div role="alert" aria-live="assertive">Your session will expire in 60 seconds.</div>
Note that I’ve included both role=”alert” and aria-live=”assertive” at the same time. These are
synonymous attributes, but some screen readers only support one or the other. By using both
simultaneously we therefore maximize the chances that the live region will function as expected.Source – Heydon Pickering ‘Some practical ARIA examples’
