Vista - Can a pre-existing SOAP tail wag the WCF dog?

I'm trying to map Zimbra's existing SOAP API to WCF. It's not working
out too well. Here's an edited sample of the SOAP requests that I
would like my WCF service to accept:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header>
<context xmlns="urn:zimbra">
<userAgent name="ZimbraWebClient - FF2.0 (Win)"
version="undefined"/>
<nosession/>
<format type="js"/>
</context>
</soap:Header>
<soap:Body>
<AuthRequest xmlns="urn:zimbraAccount">
<account by="name">user1</account>
<password>test123</password>
</AuthRequest>
</soap:Body>
</soap:Envelope>

I've tried several approaches, the most promising being a
MessageContract, but it's not working out all that well. First, I
don't know if WCF is going to accept anything that doesn't have an
Action element on the header. If that's the case, it wouldn't be too
difficult to tag an Action header onto the request on Zimbra's side of
the fence. Second, I can't figure out any way, even with vanilla XML
serialization, to create a simple element with an attached attribute
(see the "account" element above). If I can't do that, then I'm
pretty well dead in the water because that pattern is all over the
API.

If I can build a service that accepts the SOAP request listed above,
it should be simple for me to repeat the pattern for the rest of the
API. Any help?

The Message Contract would be your best bet here.

And yes, an Action must be applied to the Message for WCF to determine what
to do with it.

Within your Message Contract, use a custom class for your header of the
"Content" section, and use a custom class for the Body of the Message
Contract. For the Body use a custom class for the "AuthRequest" section that
uses the XmlSerializer instead of the DataContract Serializer.

In the Custom "AuthRequest" class the [XmlFormatter] attribute and apply the
name property/field as a [XmlAttribute] markup.
