UMLR — Not clear when to use ExecutionOccurrenceSpecification with ExecutionSpecification

  • Key: UMLR-517
  • Legacy Issue Number: 18037
  • Status: open  
  • Source: Oracle ( Darren Kumasawa)
  • Summary:

    Location:
    Page #607, 17.2.3 Semantics, Execution Specifications
    Page #619, 17.5.3 Semantics, Execution Occurrence Specifications
    Title: Not clear when to use ExecutionOccurrenceSpecification with ExecutionSpecification

    Summary:
    Page #607, 17.2.3 Semantics, Execution Specifications
    "Typically the start occurrence and the finish occurrence will represent OccurrenceSpecifications such as a receive OccurrenceSpecification (of a Message) and the send OccurrenceSpecification (of a reply Message)."

    Page #619, 17.5.3 Semantics, Execution Occurrence Specifications
    "A ExecutionOccurrenceSpecification represents, on a lifeline, the start event or the end event of an ExecutionSpecification."

    When should ExecutionOccurrenceSpecifications be used as start and finish of ExecutionSpecification, and when should Message/Destruction OccurrenceSpecifications be used instead? The ExecutionOccurrenceSpecification is the only one that has a reference back to ExecutionSpecification. Is there a guideline of when to use one over the other?
