If you don't use a targetNamespace, none of your Elements or Attributes should be in a namespace, however at the moment your Elements and Attributes are defined in the XMLSchema namespace. Xerces-J 2.5.0 does complain about this (and I think this is correct), I don't know why XSV does not complain about this. The following however is valid according to Xerces: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3.org/2001/XMLSchema"> <element name="A"> <complexType> <all> <element ref="B"/> </all> </complexType> </element> <element name="B"/> </schema> However you probably don't want your elements to be in the XML Schema namespace. If you don't want to declare a targetNamespace, use this: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="A"> <xs:complexType> <xs:all> <xs:element ref="B"/> </xs:all> </xs:complexType> </xs:element> <xs:element name="B"/> </xs:schema> If you want to declare a targetnamespace you could use this: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="test" targetNamespace="test"> <xs:element name="A"> <xs:complexType> <xs:all> <xs:element ref="B"/> </xs:all> </xs:complexType> </xs:element> <xs:element name="B"/> </xs:schema> Or if you want the schema elements to be in the default namespace: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="test" xmlns:test="test"> <element name="A"> <complexType> <all> <element ref="test:B"/> </all> </complexType> </element> <element name="B"/> </schema> By the way I made a mistake in my previous email, the positiveInteger type should be referencing a type in the schema namespace so it should look like this: xs:positiveInteger Regards, Edwin Dankert Cladonia Ltd. http://www.cladonia.com/
