That's what I was thinking.  Let the field be free text, but also 
include some recommended values in the spec.

That's a good point.  For example if a user is using geode to generate 
lat/lon based on visible wifi access points, we could have something like:

<geoloc xmlns='http://jabber.org/protocol/geoloc' xml:lang='en'>

Otherwise, placing 'geode' in the source element would mask the actual 
location source.

Same thing for other providers like Fire Eagle, etc.
