Definition for tracing execution of an iterative activity. Currently used also for tracing handling of asynchronous updates. (Although not all its features are used there!)

Item Summary
Name	Type	Multiplicity	Description
order	property int	[0,1]	Order in which this definition is to be considered.
interval	property int	[0,1]	Traces processing of each N-th item.
beforeItemCondition	container BeforeItemConditionType	[0,-1]	Conditions that must be fulfilled (any of them) before this definition is applied.
afterItemCondition	container AfterItemConditionType	[0,-1]	Conditions that must be fulfilled (any of them) for the result of this tracing be written to the file.
tracingProfile	container TracingProfileType	[0,1]	Tracing profile to be used.
tracingPoint	property TracingRootType	[0,-1]	Point(s) to be traced.

Items
- order
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Order in which this definition is to be considered. Nulls go last.
- interval
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Traces processing of each N-th item. DEPRECATED. Use beforeItemCondition instead. (Except for tracing asynchronous updates. There, only this property is observed.)
- beforeItemCondition
  
  Flags: RAM,runtime
  
  Multiplicity: [0,-1]
  
  Conditions that must be fulfilled (any of them) before this definition is applied.
- afterItemCondition
  
  Flags: RAM,runtime
  
  Multiplicity: [0,-1]
  
  Conditions that must be fulfilled (any of them) for the result of this tracing be written to the file. BEWARE! This condition is checked only for traces with the root of activityItemProcessing, i.e. those that were started right on the level of the iterative activity.
- tracingProfile
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Tracing profile to be used.
- tracingPoint
  
  Flags: RAM,runtime,AVals:6
  
  Multiplicity: [0,-1]
  
  Point(s) to be traced.
