In-Depth Information
In fact, the default behavior should be relevant="additions text" . This reflects the
most common type of changes.
ARIA live regions provide a standardized way to alert assistive technology that a DOM
change has occurred and tell it how to handle the change.
You may also prevent updates from being announced until all of the changes in a live
region finish updating by changing the live region's state. You do this by dynamically
setting the attribute state ( aria-busy="true" ) and then clearing it when the updates are
ready to be announced. This might be useful when multiple updates in a live region
need to be announced together to make sense.
