Andrew, Anton, I am using Andrew's message to reply to both. I concur with Andrew, please see below...

Other than Andrew, I think we should remove/change most of the text, as indeed only PRI is available on an universal basis. Samples of different message formats can be used to convey that information. > We get asked so often by customers if we are 3164 compliant.

Andrew has a very valid point here. We experience the same quite often. We even added an option "use RFC 3164 compatible format" to our product and guess what - it is turned off most of the time because RFC 3164 does not describe what receivers and senders typically do ;). Even if we obsolete 3164 with -protocol, I know a lot of folks will come and ask "Hey, do you support the old standard that most of my other devices use?". They simply will not care about it being obsoleted by something different. However, if we go ahead and crate 3164bis (another informational document), the situation will IMHO change. Now there is a newer "standard" (as people perceive it) for the "old" syslog. And if that says "You can not trust anything but PRI" I can "sell" that. Plus, I have a very good point in argumenting why syslog-protocol is superior. I know I am not talking hard technical facts here. I am talking real life. Most people do not care if a RFC is informational or standards track. If it is a RFC, it must be something products comply too. I agree that implementors should understand the difference. They (hopefully/probably) do. But do implementors actually decide what to implement? No - not in my experience. The marketing department tells them what to do. And customers tell the marketing department. And guess what? These customers are the informed masses that do *not* know the inner workings of the IETF (aka "a RFC is a RFC is a RFC..."). Even in a technical context like the IETF I think a little bit of real-world politics can be considered. It is the key to acceptance of new standards.
