Your document is valid. Two <Buch> elements, two distinct ID fields. What's the problem? If I edit your instance so both of the ID fields are identical, then XSV raises an error: <Liste xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="T.xsd"> <Buch> <ID>1</ID> <Name>Buch1</Name> </Buch> <Buch> <ID> 1 </ID> <Name>Buch2</Name> </Buch> </Liste> <invalid char="4" code="cvc-identity-constraint.2.1.2" line="7" resource="file:///amd/nfs/rhymer.cogsci.ed.ac.uk/export/ltg/users/ht/xml/xmlschema/monk/buch.xml">duplicate key 1 for {None}UNIQUE_Buch, first appearance was in unnamed entity at line 3 char 4 of file:///amd/nfs/rhymer.cogsci.ed.ac.uk/export/ltg/users/ht/xml/xmlschema/monk/buch.xml</invalid> </xsv> -- Henry S.
