定义元素的内容类型以及可枚举属性

Question

我在定义元素的内容类型（“phonenumber”）时遇到了问题，同时定义了具有枚举限制的属性（“位置”）。

这里就是我卡：

<xs:element name="phonenumbers"> 
    <xs:complexType> 
     <xs:sequence maxOccurs="unbounded"> 
      <xs:element name="phonenumber"> 
       <!-- 
       Try #1: 
       Define the type of the attribute "location" and the 
       content-type of the element "phonenumber". But without 
       enumeration restrictions on "location". 
       --> 

       <xs:complexType> 
        <xs:simpleContent> 
         <xs:extension base="xs:integer"> 
          <xs:attribute name="location" type="xs:string"/>               
         </xs:extension>              
        </xs:simpleContent> 
       </xs:complexType> 

       <!-- 
       Try #2: 
       Enumerables in attribute "location" with no content-type 
       of the element "phonenumber", thus being unable to put 
       anything in it. 
       --> 

       <xs:complexType>             
        <xs:attribute name="location"> 
         <xs:simpleType> 
          <xs:restriction base="xs:string"> 
           <xs:enumeration value="Home"/> 
           <xs:enumeration value="Work"/> 
           <xs:enumeration value="Mobile"/> 
          </xs:restriction> 
         </xs:simpleType> 
        </xs:attribute> 
       </xs:complexType> 

      </xs:element> 
     </xs:sequence> 
    </xs:complexType> 
</xs:element>

什么

<xs:element name="phonenumbers"> 
    <xs:complexType> 
    <xs:sequence> 
     <xs:element name="phonenumber" minOccurs="0" maxOccurs="unbounded"> 
     <xs:complexType> 
      <xs:simpleContent> 
      <xs:extension base="xs:integer"> 
       <xs:attribute name="location" use="required"> 
       <xs:simpleType> 
        <xs:restriction base="xs:string"> 
        <xs:enumeration value="Home"/> 
        <xs:enumeration value="Work"/> 
        <xs:enumeration value="Mobile"/> 
        </xs:restriction> 
       </xs:simpleType> 
       </xs:attribute> 
      </xs:extension> 
      </xs:simpleContent> 
     </xs:complexType> 
     </xs:element> 
    </xs:sequence> 
    </xs:complexType> 
</xs:element>
