Could you provide XML Schema (XSD) for XML configuration files ? In Eclipse there is smart code completion for XML files associated with XSD, I found for Log4j there is DTD: http://wiki.apache.org/logging-log4j/Log4jXmlFormat I found some discussion here: http://www.mail-archive.com/logback-user@qos.ch/msg00055.html "There is no DTD to logback configuration files because this is pretty difficult to give a description that is not too strict of the possibilities that the components of logback may offer. " Actually DTD is very primitive, I think that XSD is much more appreciate way. I prepared XSD for Open Street Map (http://forum.openstreetmap.org/viewtopic.php?id=7186), please let me know if you interested in my any help. Regards, Grzegorz Szpetkowski
