Description
Expand the initial note, to make it clearer that authors should really have an empty container first, and then inject a message into it.
It also gives a nod to the slightly "magic" behavior that browsers/screen readers have when it comes to
role="alert".This also corrects the current error regarding
aria-live="off"- see w3c/aria#2144 for a clarification onaria-live="off"... it doesn't mean "don't announce changes", but rather "announce them only when focus is on the element"Motivation
Expanding the note helps further clarify how to use live regions.
Correcting the
aria-live="off"problem ... well ... corrects a common misconception/problem (caused by the spec using an unintuitive value, which hopefully will be addressed at spec level soon)Additional details
