Hi, If you have an IDREF attribute in the schema it is not required for that schema to define an ID attribute. However, when you validate an instance document the value for the IDREF attribute needs to be specified in a component (element or attribute) that have an ID type or a type derived form ID. The part of the specification related with this is http://www.w3.org/TR/xmlschema-1/#cvc-id *** 1 There must be no ID/IDREF binding in the item's [ID/IDREF table] whose [binding] is the empty set. *** Best Regards, George --------------------------------------------------------------------- George Cristian Bina <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com Karr, David wrote: > This may be a trivial question in this audience, but if you have an > attribute defined in the schema as "xs:IDREF", does there also have to > be at least one attribute defined in the schema as "xs:ID", and a > similar relationship in the XML instance document, with the IDREF value > matching at least one ID attribute?
