Hello, I'd like to propose that we add an element called SystemProperty to our configuration. This would look like our current Property element but would set a system property instead of a configuration property.
My use case is, at work, our tooling generates one XML configuration file for a user's project and additional XML files for each DTAP environment. The main Log4j configuration file uses XInclude to bring in the appropriate DTAP file. Depending on the configuration of the user's project, and in light of Log4j's use of system properties, specifically, our new enableJndi* system properties, it would be nice to be able to say in DTAP XML files something like <SystemProperty key="enableJndiJms>true</SystemProperty> or whatever Property supports. Thoughts? Gary
