xml log4j

The original documentation was available at http://wiki.apache.org/logging-log4j/Log4jXmlFormat

The wiki is in maintenance at the moment, so I cannot verify that the link is still valid. You will find the document at archive.org: http://web.archive.org/web/20121024061840/http://wiki.apache.org/logging-log4j/Log4jXmlFormat
