Payload-factory Mediator

Payload-factory mediator creates a new SOAP payload for the message, replacing the existing one. printf() style formatting is used in the mediator configuration to create the new payload. New payload format and necessary arguments could be provided through the UI.

Each argument could be a static value or an XPath expression. When an expression is used, argument value is fetched at runtime by evaluating the provided XPath expression against the existing message.
