[logback-user] Are special charcters allowed in logger configurations?

Hi, I would like to know if the following issue is resolved in logback, it was previously encountered in log4j: "there are known issues with using this naming convention (with square brackets) in log4j XML based configuration files" I am using a similar configuration with square brackets: logger name="org.apache.catalina.core.ContainerBase.[Catalina].[localhost]" level="INFO" additivity="false"> But it appears that the portion after ContainerBase is being ignored or not processed. I would really appreciate any help on this. Thanks Noman A.
