Yes, but how is that interoperable? I want my implementation to be
interoperable with every other implementation out there.

How do I know programmatically this is the geolocation node? Imagine two
people each in separate rooms each attempting to create a XMPP application
that will exchange XEP-0080 geoloc data (without using PEP). How would
implementation A know which node implementation B publishes their
geolocation data to?

Maybe I am missing something in the pubsub spec that explains how this is
discovered.
