Right. So you want something like this:

<message
   to="juliet at example.com/balcony"
   from="romeo at example.net/orchard"
   type="chat">
   <body>
     Juliet, I am at 47.8N,9.3E and feeling kind of dizzy!
   </body>
   <html xmlns='http://jabber.org/protocol/xhtml-im'>
   <body xmlns='http://www.w3.org/1999/xhtml'>
       <p>
         Juliet, I am at <a href='geo:some-geo-uri'>47.8N,9.3E</a>
         and feeling kind of dizzy!
       </p>
     </body>
   </html>
   <geoloc xmlns='http://jabber.org/protocol/geoloc' xml:lang='en'>
     <country>Italy</country>
     <lat>47.8</lat>
     <locality>Venice</locality>
     <lon>9.3</lon>
   </geoloc>
</message>

(Or instead of using XEP-0080 format you can embed some Geography Markup 
Language XML or whatever you like for your application.)
