        <documentation>A Value Array is used for homogeneous arrays of primitive and aggregate values.   _ScalarValueList is preferred for arrays of Scalar Values since this is more efficient.  Since "choice" is not available for attribute groups, an external constraint (e.g. Schematron) would be required to enforce the selection of only one of these through schema validation</documentation>
