I think I want to use xs:key as opposed to xs:unique because xs:key cannot be NULL. OK, here's my schema fragment: <xs:complexType name="sectorType"> <xs:sequence> <xs:element name="id"> <xs:simpleType> <xs:restriction base="xs:integer"> <xs:minInclusive value="1"/> <xs:maxInclusive value="10"/> </xs:restriction> </xs:simpleType> <xs:key name="sec_id"> <xs:selector xpath=".//sector"/> <xs:field xpath="id"/> </xs:key> </xs:element> <xs:element thing1 …/> <xs:element thing2 …/> <xs:element thing3 …/> </xs:sequence> </xs:complexType> <xs:element name="sector" type="sectorType" minOccurs="1" maxOccurs="10"> There are no more than 10 sectors, numbered 1 thru 10. But the following XML file comes up valid. What did I miss ? <?xml version="1.0" encoding="UTF-8"?> <foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="foo.xsd"> <sector> <id>1</id> <thing1>…</thing1> <thing2>…</thing2> <thing3>…</thing3> </sector> <sector> <id>2</id> <thing1>…</thing1> <thing2>…</thing2> <thing3>…</thing3> </sector> <sector> <id>1</id> <thing1>…</thing1> <thing2>…</thing2> <thing3>…</thing3> </sector> </foo>
