ACTION-1011: updating example for 2.9.1

Per ACTION-1011 I was supposed to update an example for 2.9.1 (Adjustable Timeout Limits) in response to comment SB05. However, SB05 isn't really about this, and other than copy editing (replacing "closes" with "chooses"  and replacing "User" and "they" with a real name and pronoun) I'm not sure what about it needs to be changed. The Example reads:

    "User closes the Exit command on their web browser, which displays a message box asking if they're sure they want to exit, with a timer saying it will assume yes if they don't respond within 10 seconds. User changes settings in their user options to turn off this timeout."


However, both examples are similar to each other. Perhaps we should have one about extending timeouts instead of turning them off altogether.

I also think that the Intent should be greatly expanded to clarify what is meant by the various exceptions, especially "Real-time Exception: The time limit is a required part of a real-time event and no alternative to the time limit is possible" and "Essential Exception: The time limit is essential and extending it would invalidate the activity". It was easier to come up with examples for these when the SC applied to content, but now that it's only about the user agent user interface, it's not so obvious. Can others help with examples?

     Thanks,
