XML Schema allows you to have attributes in an xsd:restriction - from  
a non-schema namespace.

So this is possible:

	
  <xsd:element name="country-codes">
	<xsd:simpleType>
		<xsd:restriction base="xsd:string" codeList:externalList="http:// 
foo/country.list"/>
	</xsd:simpleType>
  </xsd:element>
