Adding fault to a wsdl

Hi,

The fault message definition is missing from my service WSDL. I would like to add these bold styled text to my WSDL. How can I do that? The aim is when I get  the WSDL of MyService with ?wsdl URL the response contains the bold styled text.

For example:

    <message name="MyFault">
        <part name="MyFault" element="s1:MyFault"/>
    </message>
    <message name="myOperationSoapIn">
        <part name="myOperationRequest" element="s1:myOperationRequest"/>
    </message>
    <message name="myOperationSoapOut">
        <part name="myOperationResponse" element="s1:myOperationResponse"/>
    </message>
    <portType name="MyServiceSoap">
        <operation name="myOperation">
            <input message="s0:myOperationSoapIn"/>
            <output message="s0:myOperationSoapOut"/>
            <fault message="s0:MyFault" name="MyFault"/>
        </operation>
    </portType>
    <binding name="MyServiceSoap" type="s0:MyServiceSoap">
        <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
        <operation name="myOperation">
            <soap:operation soapAction="http://test.com/ns/MyService/v1/myOperation" style="document"/>
            <input>
                <soap:body use="literal"/>
            </input>
            <output>
                <soap:body use="literal"/>
            </output>
            <fault name="MyFault">
                <soap:fault use="literal" name="MyFault"/>
            </fault>
        </operation>
    </binding>

Thanks,
