No role required.
The **ariaRelevant** setting gives a hint about what types of changes are relevant and should be announced by assistive technology. Any change that is not relevant should be treated as if the region had [**ariaLive**](/aria/attributes/aria-live)="off" and should not be announced. The default behavior is equivalent to `additions text`. Updates are announced only as nodes are added, or as text is added or removed. **Note** For cross-browser compatibility, always use the WAI-ARIA attribute syntax to access and modify ARIA properties, for example `object.setAttribute("aria-valuenow", newValue)`.
