SYSML17 — Proposal to have a stereotype for reference nested property

When one needs to reference a value of a specific property of part in a composition hierarchy in order to bind it to a constraint parameter, one uses the dot notation shown in section 8.3.1.2. (Example: a box labeled myCar.myEngine.currentTemp in a parametric diagram). When such a box is binded to a constraint parameter a nested connector end may be used to reference this property in the context of the composition hierarchy. However this poses a serious implementation issue for tools since until the box is binded it has no real model element behind it, also if one copies this box or the diagram to another hierarchy in the model then the tool has to complicated analysis. We propose to have a stereotype for reference nested property similar to nested connector end in which the path in the composition hirerchy is specified (i.e. propertyPath: Property [1..*] (ordered) - like in section 8.3.2.6). This will make it easier for tools to implement backed by the standard meta-model.
