SYSML21 — Constraint checkRequirementUsageObjectiveRedefinition needs to handle feature chains

Open Closed All

  • Summary:

    The semantic constraint checkRequirementUsageObjectiveRedefinition requires that

    A RequirementUsage whose owningFeatureMembership is a ObjectiveMembership must redefine the objectiveRequirement of each CaseDefinition or CaseUsage that is specialized by the owningType of the RequirementUsage.

    But this doesn't handle the case in which the owningType may be specialized by a feature chain whose featureTarget is a CaseUsage.
