Further discussion on Change of Content SC

Yes, but the “changes of context” definition includes an indication that changes of content are not always changes of context.

Sure, agreed.

So on an HTML web page does everything that is added after page load need to use aria-live in order to meet 4.1.2?

If I have a weather page and there is a content section that is updated every 10 minutes with the new weather, what SC requires that it use aria-live to notify the end user?

I wouldn’t think that in your case that the submit button “triggers” it - it is the validation issue on a control that triggers the message. This could be clarified, I agree.

I’m still seeing a gap. I agree that many form/UI component-based scenarios are covered by 4.1.2, there is a lot of content that isn’t covered by 4.1.2.
