RE: Proposed SC on notification of dynamic changes to apage

David,

Two things:

1) Should we also consider “changes in context which could be additional content that would change the context of the already understand or programically available information?”

Changes in content can change context as noted in the various supporting documents for WCAG 2.0 3.2.2 On Input.

I see radio buttons that display further questions on health websites that not only display new questions but these questions themselves put the original question in a new context. 

Do you smoke? Yes/no. No would not change the context but yes would because it will change the entire premise of the questions and end result of the survey and result of the questions due to changes in health rates, and other items. The previous questions would have been in the context of just personal information, but this question introduces a change in context as it would be indicating changes in coverage or rates, etc.

2) Can you also please add a definition of the final part of this SC?

“if the changes do not immediately follow the control that triggered the change. (Level AA)”

Thank you.

Alan

Subject: Proposed SC on notification of dynamic changes to apage

Here's a proposed wording for the dynamic content Success Criterion on dynamic content

=====
SC x.x.x.x Change of content: Programmatic notification is provided for changes in content that convey information, or indicate an action was taken, if the changes do not immediately follow the control that triggered the change. (Level AA)
=====
Definitions
Programmatic notification: Notification by software from data provided in a user-agent-supported manner such that the user agents can extract and present this notification to users in different modalities, without further action by the user, beyond focusing on, or activating the control which caused the change.
Change of content: Changes made to a web page after it has been delivered to the user agent.
