Hey Peter They are there since when log4net was invented and they are not undocumented. See:
http://logging.apache.org/log4net/release/sdk/index.html Those levels are part of the public API and allow people to implement finer granularity of logging events in cases where trace, debug, info, warn, error and fatal are not enough. You may notice that the constructor of Level allows to create even more levels than those 13 (up to 2^32 minus 2; i.e. 4294967292). If there are real-world use cases for so many log levels is written on another piece of paper. But from a framework-point-of-view it is good to support them in case someone needs them.
