Status role is marked for the container that provides an information to the user as an alert. The status role is similar to an alert role. The difference is, a status role is marked to the container whose content is useful for the user but not important to inform immediately whereas the alert role is marked for the content that needs immediate attention.
Status role is usually used for a live region. The content that is provided with the status role will have an implicit value of aria-live=”polite”
