XmlElement wrapped in extra tag in SOAP request

Hi I have a service-proxy with one method:

void SendRequest(MyMessage msg);

The MyMessage is defined as follows:

[MessageContract(IsWrapped=false)]
public class MyMessage{
    [MessageBodyMember(Order=0)]
    public XmlElement Body;

    public MyMessage(XmlElement Body){
        this.Body = Body;
    }
}

Now, the problem is that when I send the request, the Body is wrapped in a tag like so:

<s:Body>
    <Body>
         <MyMessage>
               <SomeData>Hello world</SomeData>
         </MyMessage>
    </Body>
</s:Body>

when what I really want is:

<s:Body>
    <MyMessage>
               <SomeData>Hello world</SomeData>
    </MyMessage>
</s:Body>

Can someone please help? I'm starting to become desperate! :/

EDIT: The reason I want to send XmlElement is that the service will accept a various amount of XML-formats, and will do the xsd-validation and transformation on the server-side. This is only supposed to be sort of a wrapper.

There is also no way I can have the endpoint-server simply accept the "wrong" xml-structure, as I'm not in control of that.

Alright, so it seems I had to totally abadon WCF for this to work.

What I did was to create two simple methods:

    XDocument ConstructSoapEnvelope(string messageId, string action, XDocument body)
    {
        XDocument xd = new XDocument();
        XNamespace s = "http://schemas.xmlsoap.org/soap/envelope/";
        XNamespace a = "http://www.w3.org/2005/08/addressing";

        XElement soapEnvelope = new XElement(s + "Envelope", new XAttribute(XNamespace.Xmlns + "s", s), new XAttribute(XNamespace.Xmlns + "a", a));
        XElement header = new XElement(s + "Header");
        XElement xmsgId = new XElement(a + "MessageID", "uuid:" + messageId);
        XElement xaction = new XElement(a + "Action", action);
        header.Add(xmsgId);
        header.Add(xaction);

        XElement soapBody = new XElement(s + "Body", body.Root);
        soapEnvelope.Add(header);
        soapEnvelope.Add(soapBody);
        xd = new XDocument(soapEnvelope);
        return xd;
    }

    string HttpSOAPRequest(XmlDocument doc, string add, string proxy, X509Certificate2Collection certs)
    {
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(add);
        req.ClientCertificates = certs;
        if (proxy != null) req.Proxy = new WebProxy("", true);

        req.Headers.Add("SOAPAction", "\"\"");

        req.ContentType = "text/xml;charset=\"utf-8\"";
        req.Accept = "text/xml";
        req.Method = "POST";
        Stream stm = req.GetRequestStream();
        doc.Save(stm);
        stm.Close();
        WebResponse resp = req.GetResponse();
        stm = resp.GetResponseStream();
        StreamReader r = new StreamReader(stm);

       return r.ReadToEnd();
    }

ConstructSoapEnvelope simply creates a soap-envelope with a header and a body (tailored for my needs with ws-addressing)

and the HttpSOAPRequest is a slightly modified version of the one found here: http://www.eggheadcafe.com/articles/20011103.asp

I had to modify it to accept client-certificates, in order for my SSL-communication to work..

Hope this helps someone else as well! :)
