The symplectic structure of the model and its Poisson-Lie symmetry are completely characterized by two $r$-matrices with spectral parameter. One of them is ordinary and trigonometric and characterizes the $q$-current algebra. The other is dynamical and elliptic (in fact Felder's one) and characterizes the braiding of $q$-primary fields.8 pages, LaTeX, to appear in the Proceedings of the Yokohama meeting on String theory and noncommutative geometry (March 2001)High Energy Physics - Theorytext
