The TransitionTimingConstraint element defines a timing constraint on a transition between structural elements as defined in a workflow. As such, it is a non-blocking constraint. This means that the transition is set on hold as long as the timing condition is not fulfilled, and is executed as soon as the timing condition is fulfilled.
The TransitionOID references the workflow Transition on which the constraint has to be executed.
The TimepointRelativeTarget attribute defines the planned time between the two activities defined by the transition in the worfkflow, expressed as an ISO 8601 duration.
The MethodOID attribute references a MethodDef that returns a durationDatetime. This allows to have relative timings that depend on other pieces of information, or that are complex timing calculations.
Either one of TimePointRelativeTarget or MethodOID must be present, and both must not be present at the same time.
If the value of TimePointRelativeTarget or the value returned by the method referenced by the MethodOID is a "zero time duration", the transition must be executed immediately, or within the provided time window, when provided.
Examples of "zero time duration" are "P0D", "PT0H", "PT0S".
The TimepointPreWindow attribute describes the amount of time, expressed as an ISO 8601 duration, to which the relative time between the two activities may be shortened with respect to the value in TimepointRelativeTarget or as delivered by the method referenced by MethodOID.
The TimepointPostWindow attribute describes the amount of time, expressed as an ISO 8601 duration, to which the relative time between the two activities may be elongated with respect to the value in TimepointRelativeTarget or as delivered by the method referenced by MethodOID.
