Hi All, I have a schema that contains the following: <!-- definition of the price element in the "ind" namespace --> <xs:element name="price"> <xs:complexType> <xs:sequence> <xs:group ref="util:auditElems" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="type" use="required"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="pricetype1"/> <xs:enumeration value="pricetype2"/> <xs:enumeration value="pricetype3"/> <xs:enumeration value="pricetype4"/> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="v" type="xs:decimal" use="optional"/> </xs:complexType> </xs:element> <!-- in a container element, I have a child called typeofpack, which in turn may have many presentations. For each presentation, I want them to have a unique set of prices. --> <xs:element name="typeofpack"> <xs:complexType> <xs:sequence> <xs:element name="presentation" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> : more elements snipped <xs:element ref="ind:price" minOccurs="0" maxOccurs="4"/> : more elements snipped </xs:sequence> </xs:complexType> <xs:unique name="uniqueindprice"> <xs:selector xpath="ind:price"/> <xs:field xpath="@type"/> </xs:unique> : more unique constraints snipped </xs:element> </xs:sequence> </xs:complexType> </xs:element> Now, in XMLSPY, this works as expected regardless of the number of presentation elements. As long as there are only one of each ind:price/@type occurences it works. The problem arises when I validate this with an XMLValidatingReader from the .NET framework. It seems that it disregards the scope of the unique constraint (which should be *within* each presentation element) and complains when there are occurences of the same ind:price/@type across the *whole document*. "There is a duplicate key sequence 'pricetype1' for '<urn>:uniqueindprice' key or unique identity constraint. An error occurred at file:///<path>/test.xml(715, 7)" Any ideas? Cheers, Ola Strandberg, Cut! Consulting _________________________________________________________________ Hela veckans väder http://www.msn.se/vader
