However, do so by clearly identifying critical updates versus information-only updates. Make users aware of important changes in content.Identify content that may be updated as a WAI-ARIA live region. Use the aria-live attribute on the container of the content that may be updated or, in special cases, use one of the WAI-ARIA special live region roles.For example, an update that reports an error or a problem may be considered more important than an update to a newsfeed that is shown as supplementary content to the main page. Make sure that the notification is appropriate to the type and importance of update that has taken place.
Where dynamic content is updated either automatically or in response to a user action, make sure that users are notified of this update in an accessible way.
