Anmerkung

Only one of the attributes key, name, and ref may be used.

dataFacet children are only allowed when dataRef refers with name to a datatype from the specification XML Schemas: Part 2: Datatypes.

restriction is only permitted when dataRef uses the name attribute.

Beispiel
<schemaSpec ident="myTEI"

<!-- ... -->
 <dataRef key="teidata.enumerated"/>
