If the CollectionExceptionConditionOID is provided, it references a ConditionDef that defines the circumstances under which collection of the Item may be omitted, i.e. when the FormalExpression evaluates to True. For example, a data collection instrument designed to collect data for an item 'IsPregnant' for an item group 'InclusionCriteria' may be omitted for male subjects. The referenced ConditionDef would be defined as illustrated below. When the FormalExpression evaluates to True, the Item with OID IG.ISPREG need not be collected.
