We use constraint as a general term, for anything that gives a statement about the plan... so it constraints some aspect of it... world state constraints, temporal constraints, object variable constraints, spatial constraints and anything else you want. Preconditions to us are just world state constraints (things that can be evaluated as holding or not) i.e. proposition=value (P=V) at <the time point associated with the begin of an activity.> Where V is usually true/false, but could be something else like (age austin)=21
