Remarks

ZToleranceValid determines if the current ZTolerance associated with the spatial reference is valid.  A ZTolerance is considered valid when it is well defined (not NaN) and the Z tolerance is greater than or equal to the minimum ZTolerance. The minimum allowable ZTolerance is 2.0 * ZResolution

To ensure that the ZTolerance specified is valid, call ZToleranceValid after calling ISpatialReferenceTolerance::ZTolerance.
