SysPhS: GOTCHA: By default PhSConstant maps to a Modelica parameter (not to a Modelica constant)

Because of the name PhSConstant one might expect it to map to Modelica constant, but it maps to a Modelica parameter (and can therefore be changed in between runs).

If you export to Modelica the block A shown from the MagicDraw SysML Plugin or Magic Cyber-Systems Engineer ^® (Cameo Systems Modeler^®) v19SP3 it generates:

model A
  A _A;
  model A
    Real v1;
    discrete Real v2;
    parameter Real v3;
  end A;
end A;

Note that as of SysPhS-1.1 there are no additional attributes on PhSConstant, so there's no obvious way to indeed generate a Modelica constant.
