  The dynamical generalization of the classical Yang-Baxter equation that
governs the possible Poisson structures on the space of chiral WZNW fields with
generic monodromy is reviewed. It is explained that for particular choices of
the chiral WZNW Poisson brackets this equation reduces to the CDYB equation
recently studied by Etingof--Varchenko and others. Interesting dynamical
r-matrices are obtained for generic monodromy as well as by imposing Dirac
constraints on the monodromy.
