"If a pubsub node is addressable as a JID plus node, the pubsub service
SHOULD ensure that the NodeID conforms to the Resourceprep profile of
Stringprep as described in RFC 3920."

So basically you can include just about any character in a NodeID.

BTW, NodeIDs do not have semantic meaning (they are opaque as far as the
spec is concerned), but if a given deployment wants to attribute meaning
to "/" as a hierarchical separator (or whatever) then that's their business.

And remember that not everything needs to be defined at the level of
XEP-0060. You can define your own semantics on top of that in your own
application, without requiring any modifications to XEP-0060 itself. Or
so we hope. ;-)
