Hopefully it will help someone else out. If anyone sees any problems with the steps below, please let me know. BTW, I am not sure why Step 1 is needed since Step 2 advertises the same capabilities.   STEPS TO ADD GEOLOC SUPPORT: 1) Client should respond to iq query <A href="http://jabber.org/protocol/disco#info">http://jabber.org/protocol/disco#info</A> with a stanza like: <iq type='result'...> <<query xmlns='http://jabber.org/protocol/disco#info'> <feature var='http://jabber.org/geoloc'/> <feature var='http://jabber.org/geoloc+notify'/>   2) Client should add <c> stanza to presence stanza with the proper "ver" attribute indicating geoloc support. The "ver" attribute is a SHA-1 hash of a string like: "client/pc//fooclient 1.0<<A href="http://jabber.org/protcol/geoloc<http://jabber.org/protcol/geoloc+notify">http://jabber.org/protcol/geoloc<http://jabber.org/protcol/geoloc+notify</A><"   The stanza looks something like: <presence <A href="mailto:from='romeo@montague.lit/orchard'">from='romeo@montague.lit/orchard'</A>>   <c xmlns='http://jabber.org/protocol/caps'      hash='sha-1'      node='http://www.chatopus.com'      ver='zHyEOgxTrkpSdGcQKH8EFPLsriY='/> </presence>   3) When location changes the client publishes its new location: <iq type='set' <A href="mailto:from='portia@merchantofvenice.lit/pda'">from='portia@merchantofvenice.lit/pda'</A> id='publish1'>   <pubsub xmlns='http://jabber.org/protocol/pubsub'>     <publish node='http://jabber.org/protocol/geoloc'>       <item>         <geoloc xmlns='http://jabber.org/protocol/geoloc' xml:lang='en'>           <country>Italy</country>           <lat>45.44</lat>           <locality>Venice</locality>           <lon>12.33</lon>         </geoloc>       </item>     </publish>   </pubsub> </iq> 4) Subscribers will receive: <message <A href="mailto:from='portia@merchantofvenice.lit'">from='portia@merchantofvenice.lit'</A>          <A href="mailto:to='bassanio@merchantofvenice.lit'">to='bassanio@merchantofvenice.lit'</A>>   <event xmlns='http://jabber.org/protocol/pubsub#event'>     <items node='http://jabber.org/protocol/geoloc'>       <item id='d81a52b8-0f9c-11dc-9bc8-001143d5d5db'>         <geoloc xmlns='http://jabber.org/protocol/geoloc' xml:lang='en'>           <country>Italy</country>           <lat>45.44</lat>           <locality>Venice</locality>           <lon>12.33</lon>         </geoloc>       </item>     </items>   </event> </message>   <hr />Stay up to date on your PC, the Web, and your mobile phone with Windows Live. <a href='http://clk.atdmt.com/MRT/go/msnnkwxp1020093185mrt/direct/01/' target='_new'>See Now</a></body> </html>
