This would lead to sending (potentially) huge XML fragments to the server,
for just adding 1 new person with an avatar or a "current song playing"
etc. feature. However it's the only thing so far to provide secure pubsub
events shared across multiple clients. Maybe you can at least split it up
on a per namespace basis (perhaps using the fragment part of the uri of
It surprises me none of the JEP-0060 authors are replying (or those of
JEPs depending on it, like 0084 and 0118). At least a security
