K/sub l/sub 3// form factors are studied in an analytic hard-meson approach, by use of the (8,8) model of chiral SU(3) x SU(3) symmetry breaking. The divergence form factor is required to show resonance behavior near the kappa meson mass. The ensuing resonance conditions are used to express lambda/sub 0/, the slope of the divergence form factor, and GAMMA/sub k/, the kappa width, in terms of the kappa mass. A considerable suppression of lambda/sub 0/ below its Callan--Treiman value can be obtained. Comparison is made with a previous analysis of K/sub l/sub 3// using the (3,3*)+(3*,3) model of symmetry breaking. It is suggested that one cannot rule out the (8,8) model in favor of the (3,3*)+(3*,3) at present.
