ARIA live regions
Five regions with different live settings, updating from the same source. Only the wiring differs, so the difference in what gets announced is attributable to the attribute rather than to the content. SAMPLE wording only.
aria-live="polite"
Polite: SAMPLE update 0, recorded at position 0
aria-live="assertive"
Assertive: SAMPLE announcement 0
aria-live="off"
Off: SAMPLE update 0, recorded at position 0
aria-live="polite" with aria-atomic
Atomic: SAMPLE update 0, recorded at position 0
aria-busy, toggling every update
Busy — updates should be held back.
