限制已在XSD中扩展的元素

Question

我正在尝试为要插入和更新的Web服务创建可重用的元素声明。我有以下声明：

<xs:complexType name="commonEntity">
  <xs:sequence>
    <xs:element name="id" type="snt-common:id" minOccurs="0"
                maxOccurs="1" />
    <xs:element name="createdByID" type="snt-common:id"
                minOccurs="0" maxOccurs="1" />
    <xs:element name="createDate" type="snt-common:dateTime"
                minOccurs="0" maxOccurs="1" />
    <xs:element name="modifiedByID" type="snt-common:id"
                minOccurs="0" maxOccurs="1" />
    <xs:element name="modifyDate" type="snt-common:dateTime"
                minOccurs="0" maxOccurs="1" />
  </xs:sequence>
</xs:complexType>

<xs:complexType name="contact">
  <xs:complexContent>
    <xs:extension base="snt-common:commonEntity">
      <xs:sequence>
        <xs:element name="firstName" type="snt-common:string255"
                    minOccurs="0" maxOccurs="1" />
        <xs:element name="lastName" type="snt-common:string255"
                    minOccurs="0" maxOccurs="1" />
      </xs:sequence>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

<xs:element id="update" name="ContactUpdateRequest">
  <xs:complexType>
    <xs:complexContent>
      <xs:restriction base="snt:contact">
        <xs:sequence>
          <xs:element name="id" type="snt-common:id" minOccurs="1"
                      maxOccurs="1" />
          <xs:element name="modifyDate" type="snt-common:dateTime"
                      minOccurs="1" maxOccurs="1" />
          <xs:element name="firstName" type="snt-common:string255"
                      minOccurs="0" maxOccurs="1" />
          <xs:element name="lastName" type="snt-common:string255"
                      minOccurs="1" maxOccurs="1" />
        </xs:sequence>
      </xs:restriction>
    </xs:complexContent>
  </xs:complexType>
</xs:element>

<xs:element id="insert" name="ContactInsertRequest">
  <xs:complexType>
    <xs:complexContent>
      <xs:restriction base="snt:contact">
        <xs:sequence>
          <xs:element name="firstName" type="snt-common:string255"
                      minOccurs="0" maxOccurs="1" />
          <xs:element name="lastName" type="snt-common:string255"
                      minOccurs="1" maxOccurs="1" />
        </xs:sequence>
      </xs:restriction>
    </xs:complexContent>
  </xs:complexType>
</xs:element>

我想要实现的是创建插入和更新请求，这两者都是联系限制。依次联系是commonEntity的扩展，它用作所有模式的基础。

插入工作正常，因为没有其他限制，但是对于更新，我们需要请求中的id和modifyDate（这是我们强制执行版本控制的方式）。但是，验证架构时出现以下错误：

  

类型＆＃39;＃AnonType_ContactUpdateRequest＆＃39;出错。该类型的粒子不是粒子的有效限制            基地。

好像我不能限制基本元素commonEntity中的元素。我尝试重新排序但没有成功。这是XSD的细微差别还是我错过了什么？
