SYSML2 — validateUsageOwningType constraint is too restrictive

Open Closed All
  • Key: SYSML2-301
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    The constraint validateUsageOwningType constrains the owningType of a Usage to be a Definition or Usage. However, this is two restrictive, because it prevents, e.g., a Usage from being declared within a body expression (as used with collect, select, etc.), which is a KerML Expression.

  • Disposition Summary:

    Remove the validateUsageOwningType constraint

    There does not seem to any real need for this constraint anyway, so it can just be removed.
