I understand the role of the globalizedTrigger, to provide a guard condition 
for each role that is relevant to a work unit.

However, if a work unit does not use a globalizedTrigger, and the guard 
condition is related to just one of the roles involved in a workunit, then 
does this mean that the condition at the other roles is non-observable?

In which case, does it have to determine what the first observable action of 
the workunit would be, and monitor for it, to determine dynamically if the 
workunit should be activated at that role? This would mean that additional 
validation would be required to ensure that the first observable activity 
(an interaction) was initiated from the role that was associated with the 
guard condition.

If this is true, then I think we need to add an additional rule covering 
this situation, within the workunit section of the spec.
