Since the issue is more than 12 years old. I don't think I need a fix for this anymore. I just lived with the fact that I copy/paste all appenders in my config files. But thanks anyway. You can see my usage in various logback.xmls in the invesdwin-context repositories on github: https://github.com/search?utf8=%E2%9C%93&q=invesdwin

From my perspective you can just close this issue.
