SYM11 — Modelica components having as type a connector can have a declaration equation

A component whose type is a connector can have a declaration equation. Example of a component definition in the Modelica library under Modelica.Blocks.Logical: "Modelica.Blocks.Interfaces.BooleanOutput condition=false;". A component whose type is a connector is mapped into a SysML port with a <<modelicaPort>> stereotype. The <<modelicaPort>> stereotype therefore needs an additional property to capture the declaration equation.
