[logback-user] Approaches to implement RFC5424 structured data support

As you noted this subject has come up before. It was one of the things that ultimately motivated me to go off and create Log4j 2.  I abandoned the fork at Github when it became clear that there wasn't going to be a good resolution to the issue. 

I'm not sure what value the second link has. I've gotten RFC 5424 to work with several systems including Splunk, rsyslog and syslog-ng.  FWIW, my use case is Apache Log4j 2 Flume Appender -> Apache Flume -> Apache Cassandra.  What is interesting here is that while RFC 5424 isn't strictly necessary for Flume integration, structured data is, at least for what we are using it for.
