5233	Double input prefix not accepted by the NF	Francesco Casella	Per Östlund	"Please consider the following test model:
{{{
package TestInput
connector InputConnector = Modelica.Blocks.Interfaces.RealInput;

model M
  input InputConnector c;
end M;

end TestInput;
}}}

When checking with the old front-end, {{{TestInput.M}}} passes the check. With the new FE, instead, the following error is reported:
{{{
OMCompiler/build/lib/omlibrary/BuildingSystems 2.0.0-beta/Buildings/Zones/ZoneTemplateAirvolumeMixed.mo:117:3-120:73:writable]
Error: Invalid type prefix 'input' on component airchange, 
due to existing type prefix 'input'.
}}}

Is this constraint explicitly mentioned in specification?
