Explanation of the current flow: In the given API, at the end of XML PayloadFactory we are adding "application/xml" as message-type and content-type headers. In enrich mediator, we are not doing such header changes. So the final header is "application/xml" and result is responded as XML.

[vanjikumaran]

However, there is a need for identifying the payload that is been loaded back into the message context.

Is this been addressed or fixed?
