6217	Allow checking models containing partial classes	Francesco Casella	Per Östlund	"If you check any model of the {{{Modelica.Fluid}}} library, which contains a partial medium package declaration, it fails with
{{{
[1] 11:55:14 Translation Error
[Modelica.Fluid.Interfaces: 571:7-572:53]: Medium is partial, name lookup is not allowed in partial classes.
}}}
This issue is reproduced by this MWE
{{{
package C
  model A
    B myB(redeclare package Medium = Modelica.Media.Air.MoistAir);
  end A;
  
  model B
    replaceable package Medium = Modelica.Media.Interfaces.PartialMedium;
    
    // The statement below is not valid, and leads to an error in checking the model B in OMEdit.
    parameter Modelica.SIunits.SpecificEnthalpy h_default = Medium.specificEnthalpy_pTX(
      p=Medium.p_default,
      T=Medium.T_default,
      X=Medium.X_default) ""Default enthalpy for the selected medium"";
  end B;
end C;
}}}
where {{{B}}} is checked successfully, but {{{A}}} fails check. Of course there is nothing wrong with {{{A}}}, it simply cannot be used unless the medium model is redeclared, but that doesn't make it invalid.

@perost, I'm not sure if you can fix this, or if @adrpo should take care of that, please report. Maybe we should introduce a separate API call that does (partial) instantiation for checking purposes and does not consider the constraint for simulation models."	defect	closed	blocker	1.17.0	New Instantiation		fixed		Adrian Pop Michael Wetter
