SYSML2_ — Actor and subject parameter notation not effective

Actor and subject are parameters of a use case (and also requirement in case of subject). The current notation suggests symbols completely outside the contour of the use case/requirements linked by a line segment. This is different from V1 where actors and subjects were not parameters. Ultimately the modeler is interested to see the binding of those parameters being the concrete occurrences standing for them. The parameter bindings can be graphically represented by binding connections to those external symbols. Would be more effective to treat those predefined parameters using on contour symbols like ports and parameters and bind to those.
