  Relativistic mean-field models of nuclear structure have been enormously
successful at reproducing ground-state properties of finite nuclei throughout
the periodic table using a handful of accurately calibrated parameters. In this
contribution we use powerful theoretical, experimental, and observational
constraints -- not employed in the calibration procedure -- to validate two
such models: NL3 and FSUGold. It is observed that FSUGold is consistent with
all these constraints, except perhaps for a high density equation of state that
appears mildly softer than required by astronomical observations. It is argued
that incorporating such constrains goes a long way in removing much of the
ambiguity left over from the standard calibrating procedure.
