[Standards] Using <geoloc/> in Data Form

[Michael Laukner]

What is the best way for including geographic locations in XEP-0004
data forms? I've found the following two specifications that define
suitable XMPP protocol extensions:
- XEP-0221: Data Forms Media Element (http://xmpp.org/extensions/xep-0221.html)
- XEP-0080: User Location (http://xmpp.org/extensions/xep-0080.html)

Is the following approach already XMPP standards compliant (i.a.w.
XEP-0068: Field Standardization for Data Forms):

<x xmlns='jabber:x:data' type='form'>
  [ ... ]
  <field var='location'>
    <geolocxmlns="http://jabber.org/protocol/geoloc">
       <text>Paris, France</text>
       <locality>Paris</locality>
       <country>France</country>
    </geoloc>
  </field>
  [ ... ]
</x>

or does this require a new XEP similar to XEP-0221 ?
