ASP.Net Web Service. What is the correct way to add a part element in response to a SOAP error that works for both SOAP 1.1 and SOAP 1.2?

Question

ASP.Net 2.0 Web Services automatically creates SOAP 1.1 and SOAP 1.2 bindings. However, our web service has SOAP extensions and custom exception handling that makes it possible to assume that only SOAP 1.1 bindings are used (for example, the SOAP extension uses the HTTP SOAPAction header to control behavior).

I want to fix the code that makes these assumptions and work correctly with SOAP 1.1 or SOAP 1.2. I am having a problem generating elements for our SOAP errors.

Consider the following implementation of the web method:

[WebMethod]
public void
ThrowsSoapException()
{
    throw new SoapException("This is a SOAP exception.", SoapException.ServerFaultCode);
}

Calling this through SOAP 1.1 gives the following result:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>This is a SOAP exception.</faultstring>
         <detail/>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

A call through SOAP 1.2 gives the following result:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <soap:Code>
            <soap:Value>soap:Receiver</soap:Value>
         </soap:Code>
         <soap:Reason>
            <soap:Text xml:lang="en">This is a SOAP exception.</soap:Text>
         </soap:Reason>
         <soap:Detail/>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

<soap:Fault> detail, : <detail> <soap:Detail>.

, SOAPException detail.

[WebMethod]
public void
ThrowsSoapExceptionWithDetail()
{
    XmlDocument doc = new XmlDocument();
    XmlNode detail =
        doc.CreateNode(XmlNodeType.Element, SoapException.DetailElementName.Name, SoapException.DetailElementName.Namespace);
    XmlNode custom =
        doc.CreateNode(XmlNodeType.Element, "custom", "http://example.com/xml/namespace/blah");
    custom.InnerXml = "Detail value";
    detail.AppendChild(custom);
    throw new SoapException("This is a SOAP exception with a detail element.", SoapException.ServerFaultCode, Context.Request.Url.AbsoluteUri, detail);
}

SOAP 1.1:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>This is a SOAP exception with a detail element.</faultstring>
         <faultactor>http://localhost/simplewebservice/service1.asmx</faultactor>
         <detail>
            <custom xmlns="http://example.com/xml/namespace/blah">Detail value</custom>
         </detail>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

SOAP 1.2:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <soap:Code>
            <soap:Value>soap:Receiver</soap:Value>
         </soap:Code>
         <soap:Reason>
            <soap:Text xml:lang="en">This is a SOAP exception with a detail element.</soap:Text>
         </soap:Reason>
         <soap:Node>http://localhost/simplewebservice/service1.asmx</soap:Node>
         <detail>
            <custom xmlns="http://example.com/xml/namespace/blah">Detail value</custom>
         </detail>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

A detailed section suitable for the current version of SOAP can be easily created.

using System.Xml.Linq;

XNamespace detailElementNamespace;
string detailElementName;
if (soapVersion == SoapProtocolVersion.Soap12)
{
    detailElementNamespace = "http://www.w3.org/2003/05/soap-envelope";
    detailElementName = "Detail";
}
else
{
    detailElementNamespace = "";
    detailElementName = "detail";
}

var document = new XmlDocument();
document.LoadXml(
    new XElement(detailElementNamespace + detailElementName,
        new XElement("MySection",
            new XElement("MyCode", "..."),
            new XElement("MyDescription", "...")
            )).ToString());

throw new SoapException(
    "MESSAGE",
    SoapException.ClientFaultCode,
    "ACTOR",
    document.DocumentElement);
