주석

Only one of the attributes key, name, and ref may be used on any given instance of dataRef.

Neither a restriction attribute nor a dataFacet child element may be used unless the dataRef refers to a datatype from the specification XML Schema Part 2: Datatypes Second Edition with a name attribute.
