I supposed you can make source an optinal attribute on every child of 
geoloc, but I think that would not be particularly useful and wasteful. 

If multiple sources are providing information, I would put them in 
separate geoloc elements and either bundle all the geolocs into one 
publish message, or send multiple publish messages (of course this 
depends on your transport of choice - I'm assuming pubsub here).
