XSD에서 고유 한 설정 요소

Question

다른 고유 제한 조건을 추가해야하는 다음 XSD가 있습니다.

상위 그룹 요소 내에서 고유 한 이름을 만들고 싶지만 각 WikiMeta에서 그룹을 반복 할 수 있습니다.

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xs:element name="AllMeta"> 
    <xs:complexType> 
     <xs:sequence> 
     <xs:element maxOccurs="unbounded" name="WikiMeta"> 
      <xs:complexType> 
      <xs:sequence> 
       <xs:element name="Subject" type="xs:string" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="PageTitle" type="xs:string" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="PageMetaDescription" type="xs:string" minOccurs="1" maxOccurs="1" /> 
       <xs:element name="Articles"> 
       <xs:complexType> 
        <xs:sequence> 
        <xs:element name="WikiArticle" minOccurs="1" maxOccurs="unbounded"> 
         <xs:complexType> 
         <xs:sequence> 
          <xs:element name="FileName" type="xs:string" minOccurs="1" maxOccurs="1" /> 
         </xs:sequence> 
         </xs:complexType> 
         <xs:unique name="uniqueFileName">

         <xs:field xpath="FileName"/> 
         </xs:unique> 
        </xs:element> 
        </xs:sequence> 
       </xs:complexType> 
       </xs:element> 
       <xs:element name="Groups"> 
       <xs:complexType> 
        <xs:sequence> 
        <xs:element maxOccurs="unbounded" name="WikiGroup"> 
         <xs:complexType> 
         <xs:sequence> 
          <xs:element name="Name" type="xs:string" minOccurs="1" maxOccurs="1" /> 
         </xs:sequence> 
         </xs:complexType> 
        </xs:element> 
        </xs:sequence> 
       </xs:complexType> 
       </xs:element> 
      </xs:sequence> 
      </xs:complexType> 
     </xs:element> 
     </xs:sequence> 
    </xs:complexType> 
    <xs:unique name="subject"> 
     <xs:selector xpath="WikiMeta"/> 
     <xs:field xpath="Subject"/> 
    </xs:unique> 
    <xs:unique name="fileName"> 
     <xs:selector xpath="WikiMeta/Articles/WikiArticle"/> 
     <xs:field xpath="FileName"/> 
    </xs:unique> 
    </xs:element> 
</xs:schema> 

아이디어가 있으십니까?

가시성 수준을 정의한 요소에 제약 조건을 추가합니다. 다음은 수정 된 XSD는 다음과 같습니다

시각적으로 이해하는 것이 더 쉬울 수 있습니다
