A transformation occurrence (TransformationOccurrence) denotes the activations of logical transformations due to state transitions or logical paths. A transformation occurrence can also have a time condition (timeCondition), stating the time instances when the invocation happens. If a logical transformation is invoked, its in-data will be assigned with particular values by the invocation context (inQuantification). As the consequence of transformation, the out-data will also be assigned with particular value (outQuantification).<br/><br/>Semantics:<br/>A logical transformation can only occur in a state transition or a logical path. In such an occurrence, a set of logical transformations are invoked. Given some particular quantifications of in-data (inQuantification) and time conditions (timeCondition), some the particular quantifications of out-data will be satisfied after the invocation.<br/><br/>Extension: <br/>EAElement.<br/>
