Description:
XML Schema 1.1 has introduced the attribute 'ref' on xs:key, xs:unique and
xs:keyref. While processing the following schema in XSD 1.0 mode with Xerces's
XSD 1.1 processor, a java.lang.NullPointerException is emitted when the schema
document is processed with Xerces sample jaxp.SourceValidator.
