> Configuration provides basic traceability to see where a config setting came from, but once the configuration is written out that information is written to a comment in the XML and then lost the next time the configuration is read back in.  It would really be great to be able to store a complete history of where the config came from in the XML, so that it can then be retrieved later for debugging.
