Renders the body content of a message from a template. The template can produce plain text, Json or XML. Variables in the template are substituted with values from the body, header, query parameters, etc. If the extension of a referenced template file is .xml it will use XMLTemplateEngine otherwise StreamingTemplateEngine. Have a look at the samples in examples/template.
