Hi Henning, 

http://www.xmpp.org/extensions/xep-0080.html takes an interesting approach by largely ignoring previous work on geolocation. It is just too attractive to create your own flavor of civic and geodetic location information format.  

Interestingly enough there is a full-blown solution for XMPP available as well that builds on the OMA protocols. I have to search for the reference, if someone cares. That one is far more complex than GEOPRIV. 

If you argue for simplicity then you refer to  http://www.xmpp.org/extensions/xep-0080.html. 

If you argue for functionality, different environments and interworking with existing systems then you point to the OMA extension. 

It's so easy. Translated to our work in GEOPRIV this would mean the following: If we want to convince people to use it then we just point them to the easy WLAN or enterprise case with a simple civic or a simple point representation. 

Ciao
Hannes

PS: Last November I was at a conference on mobility protocols. Someone gave a presentation on a new mobility protocol design. The author claimed it was very simple. Indeed, it was simple -- because it just didn't care about security.
