I think I can see why you are getting so confused, JEP-0060 is supposed to
be just the building block to build full featured pubsub applications, it
doesnt really seem that this JEP is really intended to be used to create a
pubsub server, as you say it leaves lots of things as optional which is fine
as it is a building block, to be useful for building a pubsub server it
might be better if we specify it in its own JEP rather than altering this
one a unnecessarly restricting future pubsub applications ontop of this,
either we need a new JEP based on JEP-0060 that locks down most of the
optionals saying all the options MUST be supported in a pubsub server or
pubsub server implementation notes need to be added to a similar effect
without altering the rest of the JEP.

Well you did say the following and I quote:

This seems to suggest that you think that a pubsub server based on JEP-0060
needs to understand the higher level protocols to work, when it clearly
doesnt if you really are understanding what parts of this relate to
implementing a pubsub server.

Also in what way does this protocol stop you from being able to create
higher level protocols based on it? I cant see any real reasons, the only
real reasons you have presented all have to do with implementing a pubsub
server, not higher level protocols, infact others dont seem to have had any
problems creating protocols that work based on JEP-0060 (User moods for
example), so your argument that you cant build protocols does not seem valid
at all as there is lots of evidence to the contrary.
