Java XML命名空间扩展导致SOAP信封中出现命名空间错误

我有一个SOAP信封，我正在其中添加一个响应负载。我已经定义了名称空间：

xmlns="http://custom.nsendpoint.com/1.1" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在响应元素中

在custom.nsendpoint.com/1.1 XSD中，有2个从基类型扩展而来的元素：

  <xs:complexType name="Contact">
    <xs:annotation>
      <xs:documentation>
        A Contact
      </xs:documentation>
    </xs:annotation>
    <xs:sequence>
      <xs:element name="EmailAddress" type="s:ContactEmailAddress" minOccurs="0" maxOccurs="1" nillable="true" />
      <xs:element name="Address" type="s:Address" minOccurs="0" maxOccurs="1" nillable="true" />
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="CompanyContact">
    <xs:annotation>
      <xs:documentation>
        Company Contact type
      </xs:documentation>
    </xs:annotation>
    <xs:complexContent>
      <xs:extension base="Contact">
        <xs:sequence>
          <xs:element name="Name" type="s:CompanyName" minOccurs="1" maxOccurs="1" nillable="true" />
          <xs:element name="Type" type="s:CompanyType" minOccurs="0" maxOccurs="1" nillable="true" />
          <xs:element name="Size" type="s:CompanySize" minOccurs="0" maxOccurs="1" />
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

  <xs:complexType name="PersonContact">
    <xs:annotation>
      <xs:documentation>
        Person Contact type
      </xs:documentation>
    </xs:annotation>
    <xs:complexContent>
      <xs:extension base="Contact">
        <xs:sequence>
          <xs:element name="Title" type="s:PersonTitle" minOccurs="1" maxOccurs="1"/>
          <xs:element name="FirstName" type="s:PersonFirstName" minOccurs="1" maxOccurs="1" />
          <xs:element name="MiddleName" type="s:PersonMiddleName" minOccurs="0" maxOccurs="1" nillable="true" />
          <xs:element name="LastName" type="s:PersonLastName" minOccurs="1" maxOccurs="1" />
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

当我深入研究

transform

方法逻辑时，我看到它在

org.apache.xml.serializer.TreeWalker

对象上调用的

traverse

方法上失败，它说：

Method threw 'org.xml.sax.SAXException' exception

如果删除联系人类型上的xsi:前缀，错误消息就会消失

谁能告诉我我做错了什么？我只是不知道我做错了什么

org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

Method threw 'org.xml.sax.SAXException' exception
