Case statements with no condition

[borismarin]

There are a couple of nml examples where Case clauses (under ConditionalDerivedVariables) are used in a if-else way, i.e. one case defines a given condition and the respecitve value, while the other has a null condition and a different value (the "else" for the previous condition). See e.g.

Should that be allowed? I don't think so. Nor does the LEMS schema
