Quantization, String Theory

a fully quantum mechanical theory would not include any quantities that are supposed to be measurable that are not represented by quantum observables, since all such quantities are actually quantum mechanical.

I think I agree with this.

What theories do you think include quantities that are supposed to be measurable but are not represented by quantum observables?

I now think I was wrong about that. From DD’s point of view a partially quantum mechanical theory is one in which you start from a classical theory and then apply a procedure called quantization to get a quantum theory.
