[JDEV] How to create a new protocol?

[Chris Chen]

Yes, depending on your needs, you can either implement your "new protocol" 
by sending under a <iq> query message or through the <x> message.

If you're using <x> messages, then all you need to do is send a message 
that is similar to:

<message to="blah" type="normal" id="id_10001">
<x xmlns="my:own:namespace">
<test>data</test>
</x>
</message>


This should work out ok.. Then you just need to parse the x message out 
from the message and handle it accordingly.  Clients who do not support 
this X Message should ignore it by default (since client X Messages are 
mostly optional).  Thus, only your clients will know how to parse it and 
will respond to such requests.

WHat you can do is read up more on the other X Messages and you'll see how 
they are sent.

And remember not to use any namespace that starts out with "jabber" or 
"jabber:x" as those are reserved.

Thanks,
Chris
