Yes. The idea is that you have categories like:
cocoon
cocoon.components
cocoon.components.store
cocoon.main
cocoon.servlet
The main category is cocoon but with any number of sub categories. You
can set individual LogTargets to those categories or have them use their
parent loggers targets. And yes there is a category "" which is the root
logger.
