SYSML2 — validateTriggerInvocationExpressionAfterArgument constraint is too strong

  • Key: SYSML2-497
  • Status: open  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    The approved resolution to SYSML2-28 includes adding the constraint validateTriggerInvocationExpressionAfterArgument, which requires:

    If a TriggerInvocationExpression has kind = after, then it must have an argument Expression with a result that conforms to the type ISQ::DurationValue.

    However, in a typical relative time trigger such as, e.g., after 10[SI::s], the result of the expression 10[SI::s] is not a DurationValue. Rather it is a ScalarQuantityValue whose mRef is the DurationUnit SI::s. Therefore, this example time trigger violates validateTriggerInvocationExpressionAfterArgument as specified in the resolution to SYSML2-28.
