The "Short users guide to log4xx" (http://logging.apache.org/log4cxx/manual/Introduction.html) describes the available levels: "debug, info, warn, error, and fatal".
The similar log4j document (http://logging.apache.org/log4j/docs/manual.html) describes these, but also an additional one: "trace". Is "trace" in log4j but not log4cxx? What would be the reason?
