(doffs shepherd hat)

I agree with Pete. There’s more to a protocol than the on-the-wire bits. Anything important for interop to work should be considered part of the protocol. Discovery is an important part of that. Changing discovery to spread functions across different servers is a change to the protocol.

Pete’s suggested fixes seem reasonable to me and relatively painless.

Ben.

It explains how to go beyond what 5222 provides by defining which order to look up the servers and what to do depending on the results received. It changes the discovery procedure defined in 5222. The fact that it is backwards compatible and doesn't break 5222 implementations is good, but it doesn't make it any less a protocol. Indeed, if it is an "optimization" of an existing protocol, that makes it a protocol. I can't see any other way of describing section 3.
