Backward Compatibility

• -protocol is NOT backward compatible to classical syslog

• If a -protocol message is received by a RFC 3164 syslogd, it will be treated as a message without header, which is moderately convenient (at least, it is a defined case and its handling makes sense).

• WG concensus was that it is more important to build a solid base than to preserve backward compatibility at all costs (http://www.syslog.cc/ietf/protocol/issue4.html)
