* <p/>
* This mediator will first get an OMELement from the source. Then put it to the current message
* according to the target element.
* <p/>
* Both target and source can specify a type. These are the types supported
* <p/>
* custom : xpath expression should be provided to get the xml
* envelope : the soap envelope
* body : first child of the soap body
* property : synapse property
* <p/>
* When specifying the source one can clone the xml by setting the clone to true. The default
* value for clone is false.
* <p/>
* When specifying the target one can replace the existing xml. replace is only valid for custom
* and body types. By default replace is true.
