[slf4j-dev] Some name restrictions for logger name?

[Libor Jelinek]

Hello all (Ceki),
are there some naming restrictions for looger name?

I would like to ("POKUSY" is Czech word for "experiments" :-))
    LoggerFactory.getLogger("_POKUSY_osgi-over-slf4j_1.0.0.qualifier")

but obtained logger is named
   _1.0.0.qualifier
