  The D=10 pure spinor constraint can be solved in terms of spinor moving frame
variables and 8-component complex null vector which can be related to the
kappa-symmetry ghost. Using this and similar solutions for the conjugate pure
spinor and other elements of the non-minimal pure spinor formalism we present a
(hopefully useful) reformulation of the measure of the pure spinor path
integral for superstring in terms of products of Cartan form corresponding to
the coset of 10D Lorentz group and to the coset of complex orthogonal group
SO(8,C). Our study suggests a possible complete reformulation of the pure
spinor superstring in terms of new irreducible set of variable.
