Dumb question:
Anisotropic out -> Subtract(1,1) -> Diffuse_Color is CoE, right?
[Q] Why Math_Function Subtract() and not Color_Math Subtract? Is Specular info numeric only?

You've found one of my cheats.

I really am not interested in the specular color - just its luminance. And truthfully, this is not a perfect implementation of CoE. What I really need is the raw specular reflectance calculated inside that node, not its final color that comes out. But there's no node that will do that. So I make the best of a bad situation.

As has been brought up many times before, if I could get at the Poser source code, I could fix the material system quite a bit.
