Before revision:  The construction relies on building Neyman-orthogonal equations that are approximately invariant to  perturbations of the nuisance parameters , including the Riesz representer for the linear functionals .
After revision:  The construction relies on building Neyman-orthogonal equations that are approximately invariant to perturbations of the nuisance parameters , including the Riesz representer for the functionals in the equations as the additional nuisance parameter .
