Getting closer. Since the term "real time event" is singular, the
definition should use singular too. Also, I suggest moving the phrase
"not recorded" to the end of the sentence to make it clear that "not
generated by the content" and "not recorded" are two different aspects
of the defintiion (at first I misread it as "not recorded ... by the
content" which of course makes no sense and was not intended)

real time event
"Real world event occurring at the same time as the viewing and not
generated by the content and not recorded."

Hmmmm

 

Building on Yvette's contribution, how about we do the following

 

1)      Add the phrase  "where time-out is essential" to  the fourth
bullet under 2.2. 

2)      Change the definition of real time event to:  

 

REAL-TIME EVENT

"Real world events that are occurring at the same time as the viewing
and are not recorded or generated by the content."  

 

For referenced that the provisions would look like:

 2.2.1 For each time-out that is a function of the content, at least one
of the following is true: [

ew.html#time-limits-required-behaviors> How to meet 2.2.1] 

*         the user is allowed to deactivate the time-out or; 

*         the user is allowed to adjust the time-out over a wide range
which is at least ten times the length of the default setting or;

*         the user is warned before time expires and given at least 20
seconds to extend the time-out with a simple action (for example, "hit
any key") and the user is allowed to extend the timeout at least 10
times or;

*         the time-out is an important part of a real-time event  where
time-out is essential to the activity (for example, an auction), and no
alternative to the time-out is possible or;

*         the time-out is part of an
<http://www.w3.org/WAI/GL/WCAG20/appendixA.html#activity-timingdef>
activity where timing is essential (for example, competitive gaming or
time-based testing) and time limits can not be extended further without
invalidating the activity.

 

2.2.4 Except for real-time
<http://www.w3.org/WAI/GL/WCAG20/appendixA.html#real-time-eventsdef>
events, timing is not an essential part of the event or activity
presented by the content. [
