    The point is that the developer can not put the data out there with the
    current syslog. At least not in a way that a log analysis tool written
    by a third party can identify it. The developer might e.g. log the host
    name of a host trying to connect to the application, but my log analysis
    tool has no way to identify that part of the log message as a host name
    without prior knowledge of the message formats generated by this particular
    application. And that is one of the things we want to change.
