Hi Dave,

I cannot reproduce your error message in oXygen 14.2 (build 2013030817) 
with this schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
elementFormDefault="qualified" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:dcmitype="http://purl.org/dc/dcmitype/">
   <xs:import namespace="http://purl.org/dc/dcmitype/" 
schemaLocation="dcmitype.xsd"/>
   <xs:import namespace="http://purl.org/dc/elements/1.1/" 
schemaLocation="dc.xsd"/>
   <xs:import namespace="http://www.w3.org/XML/1998/namespace"
     schemaLocation="xml.xsd"/>
   <xs:complexType name="DCMIType">
     <xs:simpleContent>
       <xs:restriction base="dc:SimpleLiteral">
         <xs:simpleType>
           <xs:restriction base="dcmitype:DCMIType"/>
         </xs:simpleType>
         <xs:attribute ref="xml:lang" use="prohibited"/>
       </xs:restriction>
     </xs:simpleContent>
   </xs:complexType>
</xs:schema>

Neither saxon nor xerces raise an error.

Could you check your build version?

Regards,

Maik Stührenberg
