The mixing between nonstrange and strange quark wavefunctions in the $\omega$ and $\phi$ mesons leads to a small predicted branching ratio $\b(D s^+ \to \omega e^+ u e) = {\cal O}(10^{-4})(\delta-3.34^\circ)^2$, where $\delta$ is the mixing angle. The value $\delta = -3.34^\circ$ is obtained in a mass-independent a
