java - ct-props-更正解析模式时的错误

Question

我正在使用 JAXB xjc 工具从 xsd 生成一些 Java 接口(interface)文件。我遇到了一个问题，我收到了大量以下形式的错误:

org.xml.sax.SAXParseException: ct-props-correct.4: Error for type 'COCT_MT110200CA.PayeeRole'. Duplicate attribute uses with the same name and target namespace are specified. Name of duplicate attribute use is 'nullFlavor'.

架构的相关部分如下:

 <xs:complexType name="COCT_MT110200CA.Holder">
  <xs:sequence>
     <xs:group ref="InfrastructureRootElements"/>
     <xs:element name="payeeRole" type="COCT_MT110200CA.PayeeRole" minOccurs="1" maxOccurs="1">
     </xs:element>
  </xs:sequence>
  <xs:attributeGroup ref="InfrastructureRootAttributes"/>
  <xs:attribute name="nullFlavor" type="NullFlavor" use="optional"/>
  <xs:attribute name="typeCode" type="ParticipationType" use="optional" fixed="HLD"/>
</xs:complexType>

其中 COCT_MT110200CA.PayeeRole 定义为:

<xs:complexType name="COCT_MT110200CA.PayeeRole">
  <xs:sequence>
     <xs:group ref="InfrastructureRootElements"/>
     <xs:element name="id" type="II" minOccurs="0" maxOccurs="unbounded">
     </xs:element>
     <xs:choice>
        <xs:element name="payeePerson" type="COCT_MT110200CA.PayeePerson" nillable="true"
                    minOccurs="0"
                    maxOccurs="1">
        </xs:element>
        <xs:element name="payeeOrganization" type="COCT_MT110200CA.PayeeOrganization"
                    nillable="true"
                    minOccurs="0"
                    maxOccurs="1">
        </xs:element>
     </xs:choice>
  </xs:sequence>
  <xs:attributeGroup ref="InfrastructureRootAttributes"/>
  <xs:attribute name="nullFlavor" type="NullFlavor" use="optional"/>
  <xs:attribute name="classCode" type="RoleClass" use="optional" fixed="PAYEE"/>
</xs:complexType>

有什么想法吗？我自己不认为这有什么问题......

哦，我想我明白了，那里有一个讨厌的属性组(InfrastructionRootAttributes)，并且在该属性组中是 nullFlavor 重复项...
