WCF receiving a request with a SWA payload

We have a requirement to build a WCF web service that uploads a document into Sharepoint. Our Enterprise service Bus is a IBM product called WPS (websphere process server) and the request is coming from is another IBM product call BTT ( Bank Transformation Toolkit). both of these products, 开发者_如何学Cin there installed version, do not support MTOM but they do support SwA. We are now investigating building a custom binding to support SwA. Has anyone tried this and able to share there experience?

If you want to use SOAP with Attachments instead of MTOM you need custom message encoder = custom channel used in custom binding. You can build your own following SwA specification or you can try this one from CodePlex.
