Step 1 is required, because when someone asks what your caps hash means, you have to be able to answer. It's important that the results from step 1 match the stuff that is hashed in step 2. > STEPS TO ADD GEOLOC SUPPORT: > 1) Client should respond to iq query http://jabber.org/protocol/disco#info > 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'/> Only include http://jabber.org/geoloc if you expect people to send you iq's in the geoloc namespace directly.

They take care of the subscribe side. _______________________________________________ JDev mailing list FAQ: http://www.jabber.org/discussion-lists/jdev-faq Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: [EMAIL PROTECTED] _______________________________________________
