The default value is text/xml in the > case of the xml output method, text/html in the case of the html and xhtml > output methods, and text/plain in the case of the text output method. This fails to mention what the media type should be for the other standard output methods: json and adaptive. I'm not sure about adaptive (implementation-defined?), but json should probably have the proper IANA encoding: "application/json".
