Esquema XML: elemento A, elemento B ou ambos

  • 772

Estou tentando escrever uma construção de esquema XML que permitiria ter o elemento A ou o elemento B, ou A e B.

Eu tentei isso:

<xs:complexType name="RoleMapType">
    <xs:sequence>
        <xs:element minOccurs="0" name="Description" type="xs:string"/>
        <xs:element minOccurs="0" name="Schedule" type="xs:string"/>
        <xs:choice>
            <xs:element name="Loader" type="RoleMapLoaderType"/>
            <xs:element name="Dump" type="RoleMapDumpType"/>
            <xs:sequence>
                <xs:element name="Loader" type="RoleMapLoaderType"/>
                <xs:element name="Dump" type="RoleMapDumpType"/>
            </xs:sequence>
        </xs:choice>
    </xs:sequence>
</xs:complexType>

mas estou recebendo um erro dizendo que Loader e Loader seriam ambíguos.

Como posso impor tal restrição?

    Eu acho que o seguinte não é considerado ambíguo:

    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  
<xs:complexType name="RoleMapType">
    <xs:sequence>
        <xs:element minOccurs="0" name="Description" type="xs:string"/>
        <xs:element minOccurs="0" name="Schedule" type="xs:string"/>
        <xs:choice>
          <xs:sequence>
            <xs:element name="Loader" type="RoleMapLoaderType"/>
            <xs:element name="Dump" type="RoleMapDumpType" minOccurs="0"/>            
          </xs:sequence>
          <xs:element name="Dump" type="RoleMapDumpType"/>
        </xs:choice>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="RoleMapLoaderType"/>

<xs:complexType name="RoleMapDumpType"/>

</xs:schema>
