Modifiers are not completely implemented (from MathCore)

[krsta]

Not all modifiers included in the soecificication are implemented yet. Most of these rules are covered by the following test cases:

DisturbedResistance3.mo 
DisturbedResistance4.mo 
ModificationXX.mo
ModifyConstantX.mo 
ModifyUnknownX.mo 
OverWritingX.mo 

We have to go through these test cases and implement needed support as well as checking as this corresponds to the Modelica spec.

Modelica specification (section 7.4.2) forbids duplicate modifications of the same element. OMC does the checking for duplicate modification, but only produces a warning, not an error, and only in the case of overlapping index modifications, like
A a(z=zeros(2), z[1]=1);

In the case of usual duplicate modifications, like
A a(x=1, x=2)

it does not even produce a warning.

Should it be fixed or is it another case of "specification forbids this, but we have to have it, so only a warning instead of an error"?

All of the tests mentioned are working, so I think it's time to close this old ticket.
