The polynomials under consideration are characterized by a factorized weight function satisfying certain analyticity assumptions. As an application, the large-degree asymptotics of the Koornwinder-Macdonald BC_N-type multivariate Askey-Wilson polynomials is determined.13 pages, LaTeXClassical Analysis and ODEsMathematical Physics33D52; 41A60text
