Given that properties are open-ended (you can have many many properties) it is actually not trivial at all to arrange them in an inheritance hierarchy.
One simple approach is to have hierarchy-wide properties which can be either set through config file or programmatically.
As in,
LogManager.getLoggerRepository().setProperty("someprop", "someval");
Thomas, would that suit your needs?

I agree we need support for this sort of cross-thread context information....properties which are inheritable through the logger hierarchy may fit the bill..I haven't looked into implementation details, but here's an example:
If you got the "org.apache.log4j" logger and called 'setProperty("someprop", "someval"), then all loggers under org.apache.log4j would also have the property (you would also need support for removeProperty("someprop")). The property would be overridden if a closer ancestor set the property (if org.apache.log4j.net set the same property).
Opinions dev folks?

Log4j gurus,
Does log4j have support for MDC/NDC across other contexts than threads? If not, is it any plans to implement this? For the time being I find my self having to prefix log messages with context sensitive information, and it doesn't really "feel" right at all.
Any suggestions for a MDC/NDC framework allowing arbitrary contexts would be much appreciated, and also how to incorporate it into PatternLayout etc.
