SYSML16 — Inability to represent dependent, independent parameters on constraint properties

Parametrics provide a powerful capability for representing constraints on properties. However, they currently do not allow a modeler to specify or notate dependent and independent parameters on a usage of a constraint property. This will enable the modeler to better express the nature of the constraint in many usage situations. The recommendation is to stereotype constraint parameters so that they can be designated as in, out, or in-out if desired. They can also be left unspecified as they are in the current parametric diagram. Proposed Solution. Add a stereotype called constraint parameter that extends property, with a stereotype property that can be in, out, in-out, or unspecified. Consider including the desctiption in the diagram extension for the parametric diagram in 10.3.1.2, adding the stereotype in 10.3.2, the diagram elements in Table 10.2, and updating the usage example in Fig 10.3.

To be traced to SysML20

More a natural evolution of the language, adding new features. Therefore out of scope for RTF.
Needs to be traced to SysML20 and addressed there.
