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: [

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