We study the canonical U(n-)-valued differential form, whose projections todifferent Kac-Moody algebras are key ingredients of the hypergeometric integralsolutions of KZ-type differential equations and Bethe ansatz constructions. Weexplicitly determine the coefficients of the projections in the simple Liealbegras A_r, B_r, C_r, D_r in a conviniently chosen Poincare-Birkhoff-Wittbasis. As a byproduct we obtain results on the combinatorics of rationalfunctions, namely non-trivial identities are proved between certain rationalfunctions with partial symmetries.
