[GitHub] logging-log4j2 issue #110: JsonLayout support for custom key-value pairs bei...

Github user dankirkd commented on the issue:

    https://github.com/apache/logging-log4j2/pull/110
  
    Does this support variable replacement.
    
    i.e. in PatternLayout one can do something like this:
    
    `<Pattern>%d{ISO8601}{UTC} %d{Z}{UTC} [CID:%X{conversation-id}] [%t] %-5p %c{1.} - %m%n</Pattern>`
    
    But it seems that 
    
    `<KeyValuePair key="CID" value="%X{conversation-id}"/>`
    
    or even
    
    `<KeyValuePair key="CID" value="${conversation-id}"/>`
    
    doesn't work.
