OSB defaulting Content-Type to "multipart/related" in case of attachments
I have scenario where I need to invoke a REST Webservice from OSB which accepts only media types which has "multipart/atom+xml". OSB is used for protocol transformation converting the SOAP request into the HTTP POST request with multipart. I have Proxy Service which will unwrap the message from the SOAP Body and post the same message into the payload of the Business Service and the attachment is passed 'as is' from the SOAP Service. The external REST Service Provider expects the media type to be "multipart/atom+xml", but in OSB when an attachment is present in the message, OSB is overrding the "Content-Type" proeprty to "multipart/related" inspite of me setting the "Content-Type" property of HTTP Transport Header in OSB and as result external RESTFUL Service is throwing "415-Unsupported Media Type" error. Below is the test results. One interesting thing is, it happens only when there is attachment present in the message. In case of a message which doesn't have attachment any "Content-Type" specified in the Transport Header is passed by the OSB to the external service. Any help is highly appreciated.
OSB Transport Header

Added the header <http:Content-Type>multipart/atom+xml</http:Content-Type>
