We have found a simple powerful Ansatz, interpreting the Lund symmetric-fragmentation function as a universal production density, which predicts multiplicities and momentum and P/sub T//sup 2/ distributions of the many meson and baryon flavors observed in e/sup +/e/sup -/ collisions at E/sub c.m./approx. =30 GeV almost perfectly with only two ''natural'' parameters of the Lund symmetric-fragmentation function. The model depends only on hadron masses and not on quark-level suppression factors such as s/u or qq/q. At a minimum, it provides an easy basis for the prediction of particle production rates and distributions, and may provide insight into the actual production mechanism.
