UMLR — In Sequence diagrams, the duration constraint shown as a vertical two-headed is ambiguous

Open Closed All
  • Key: UMLR-652
  • Status: open  
  • Source: Change Vision ( Michael Chonoles)
  • Summary:

    If the duration constraint goes from the midst of one message to the midst of another (e.g., the return message), it is unclear whether it is from Start Msg1 to Start Msg2, End Msg1 to End MSg2, Start1 to End Msg2, or End1 to Start Msg2.

    How should this be disambiguated
