Some other notes on changing the the configuration file in 3.x: 1. Old (2.x) cfg files will still work (translate on the fly) 2. command line tool will be provided to translate old files on the fly 3. DTD and schema will be provided to enable validation and editing using appropriate XML tools. (JBCACHE-645 ) 4. Internal semantical validation of the cfg file before startup will also be done.
