+    <p>The aria-live attribute is added to an element in the document by a 
+      script after the onload event completes with the value="polite" and 
+      the element has a child DOM element node that contains text content. 
+      After the aria-live attribute is added, the CSS 'visibility' property 
+      of the child DOM element node is changed to visibility="hidden".</p>
