Part of Item: 
Comment Type: technical
Summary of Issue: Essential Exception
Comment (Including rationale for any proposed change):
When it comes to time limits the Criterion requires at least one of a number of conditions to be true. These include, \"Essential Exception: the time limit cannot be extended without invalidating the activity.\" There appears to be no additional definition of what constitutes \"essential\" or advice on interpreting this condition.

As it stands, it appears that it would be possible to declare that any event maybe deemed to be invalidated by extending the time-limit.

Proposed Change:
The Working Group consider removing \"Essential Exception\" since it would appear that all likely essential exceptions would already be covered by the \"Real-time Exception\" condition. 

If this is not possible, the Working Group should provide a precise indication (with example) of what constitutes an Essential Exception.
