SYSML2 — Subsetting of subjectParameter properties is wrong

Open Closed All
  • Key: SYSML2-430
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    The properties RequirementUsage::subjectParameter and CaseUsage::subjectParameter in the abstract syntax SysML.xmi currently subset Behavior::parameter. However, neither RequirementUsage nor CaseUsage specialize Behavior. Rather they (indirectly) specialize Step, so the subjectParameter properties should be subsetting Step::parameter rather than Behavior::parameter.

    (Note that this error is not apparent in the specification document, because, in the annotation for subsetting, the subsetted parameter is shown without qualification – e.g., just parameter, not Behavior::parameter.)
