The identity constraints xs:unique and xs:key might meet your requirements. You define an identity constraint within a particular element, and its scope is then limited to that element. Have a look at the XML Schema Primer Section 5 for some examples: http://www.w3.org/TR/xmlschema-0/#quartelyReport Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/
