wording for interruptions

Hi Folks


we have better wording suggested at  at https://www.w3.org/WAI/GL/wiki/2.2.7_Revision It seems to address the comments we received on this issue. Does anyone have an objection to it?


I added  " contextual help overlay" to the list of exclusions to address an additional comment.


"A mechanism is available to postpone and suppress unnecessary interruptions and changes in content, unless they are initiated by the user or involve an emergency.
Definition: Unnecessary interruptions: Secondary information, pop-ups, overlays or actions that are not part of the workflow sequence or the key purpose of the application. Note: Error, success, and warning messages; a contextual help overlay; timeout notifications, live updates when the purpose of the application is monitoring are not unnecessary interruptions".


I have also put comments into all of the comments from Mike's link , hopefully they are all now addressed with the new wording. 



All the best
