xs : unique 어떻게 작동시켜야합니까?

Question

안녕하세요 XML 문서에서 고유 한 속성을 사용하고 싶습니다. XML을 시작하기 시작했습니다. 나는 각 사람에게 고유 한 ID를 부여하고 싶습니다. 나는 xs : unique를 보았지만 여기서 어디로 가는지 알아 내지 못한다. 시도 할 때마다 구문 분석을하지 않는다. 다음과 같이 스키마는 다음과 같습니다

<?xml version='1.0' encoding='utf-8'?> 
<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'> 
    <xs:element name='people' type='peopleType' /><!-- Root Element --> 

    <xs:complexType name='peopleType'> 
     <xs:sequence> 
      <xs:element name='person' type='personType' maxOccurs='unbounded'/> 
     </xs:sequence> 
    </xs:complexType><!-- End peopleType--> 

    <xs:complexType name='personType'> 

     <xs:sequence> 
      <xs:element name='name' type='nameType' maxOccurs='unbounded' /> 
      <xs:element name='email' minOccurs='1'> 
       <xs:simpleType> 
        <xs:restriction base='xs:string'> 
         <xs:pattern value='([a-zA-Z0-9_-])*([.])?([a-zA-Z0-9_-])*([.])?([a-zA-Z0-9_-])*[@]([a-zA-Z0-9_-])*([.])?([a-zA-Z0-9_-])*([.])?([a-zA-Z0-9_-])*' /> 
        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
      <xs:element name='favColour' type='colourType' minOccurs='0' /> 

     </xs:sequence> 

     <xs:attribute name='id' type='xs:integer' /> 

    </xs:complexType><!--End personType --> 

    <xs:complexType name='nameType'> 
     <xs:sequence> 
      <xs:element name='given' minOccurs='1'> 
       <xs:simpleType> 
        <xs:restriction base='xs:string'> 
         <xs:pattern value='[A-Z]([a-z])*' /> 
        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
      <xs:element name='family' minOccurs='1'> 
       <xs:simpleType>

        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
     </xs:sequence> 
    </xs:complexType><!-- End nameType --> 

    <xs:complexType name='colourType'> 
     <xs:sequence> 
      <xs:element name='red' minOccurs='1' > 
       <xs:simpleType> 
        <xs:restriction base='xs:integer'> 
         <xs:minInclusive value='0' /> 
         <xs:maxInclusive value='255' /> 
        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
      <xs:element name='green' minOccurs='1' > 
       <xs:simpleType> 
        <xs:restriction base='xs:integer'> 
         <xs:minInclusive value='0' /> 
         <xs:maxInclusive value='255' /> 
        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
      <xs:element name='blue' minOccurs='1'> 
       <xs:simpleType> 
        <xs:restriction base='xs:integer'> 
         <xs:minInclusive value='0' /> 
         <xs:maxInclusive value='255' /> 
        </xs:restriction> 
       </xs:simpleType> 
      </xs:element> 
     </xs:sequence> 
    </xs:complexType><!-- End colourType --> 
</xs:schema> 

[편집]을 내가 변경 사항은 다음과 조언을 복용 후. 그것은 괜찮은 구문 분석하지만 고유 한 특성을 적용하지 않습니다.

사람에 대한 요소 선언에서 selector xpath = "person", 필드 xpath = "@ id"로 xs : unique 선언을 추가하십시오. 작동하지 않는다면 시도한 것을 보여주십시오.
