Specification


Summary

This effort aims to create a JavaScript API so that developers can better 
notify AT users of actions/changes to a webpage not necessarily tied to UI 
elements.


Blink component
Blink>Accessibility<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EAccessibility>

Motivation

Currently the only mechanism available today that communicates content changes 
in a web app down to the accessibility layer is via ARIA live regions. One 
major limitation to ARIA live regions is that they assume the change to a 
webpage is tied to a DOM element. This leads to content authors employing 
various inefficient or inconsistent tricks and hacks to notify of changes that 
are not associated with the DOM. We propose a separate notification API to 
address these scenarios, called Confirmation of Action.
