Section 3.2 states

---
  If Message Publisher ID unicity is not preserved through the
  collection domain, the source IP address of the UDP datagram SHOULD be
  used in addition to the Message Publisher ID to identify the
  information source.
---

It seems for configured "dial-out" transports, we are missing a
definition of the source IP or interface (the latter of which would need
a selection mechanism, prior a VRF reference) which is crucial for
receivers to distinguish (generally an identity that is stable - e.g.
loopback) sources.

I've only briefed through this draft and not other transports so this
may very well apply to others as well
