title: WCF input huge XML as Stream with Content-Type: xml/text
body: <p>I have a RESTful WCF web service that processes huge XML files that are passed in as a Stream with a Header Content-Type: text/text using a POST method.  When a client tries to use this web service with a Header Content-Type: text/xml, they receive a "...contains an unrecognized http body format value 'Xml'. The expected body format value is 'Raw'.  This can be because a WebContentTypeMapper has not been configured on the binding" error.
  I am tasked with making this web service work with a Header Content-Type:text/xml as a multitude of clients use this web services with other services and do not want to change the content type just for this service.  How do I map the incoming Stream as WebContentFormat.Raw and get this web service to accept the Content-Type:text/xml?
  Thank you.</p>
