What about the concept of adding one Logger to several "Categories"? That 
would give some of the power of markers, w/o adding much complexity to the 
API.

Most logging-systemet could simply output the event to all the "attached" 
categories as if it was emitted with several distinct Loggers, while more 
elaborate systems/schemes could make for conditional configurations that 
required a log-event to be output to a particular set of categories "at 
the same time" before forwarding the event to some output-sink.
