yes and 'no' :-). Yes because nothing was done in this respect to the 
module itself. 'No' because now (kamailio 3.0) you can use 
transformations to get content of xml documents and if the body is xhtml.

You can build a new message with uac module or update the existing SIP 
message (content type, body), do msg_apply_changes():
http://kamailio.org/docs/modules/3.0.x/modules_k/textops.html#id2513318

and they use xmpp functions.

You can use ngrep to sniff the network to see connection between 
kamailio (openser) and xmpp server as well as run kamailio in debug mode 
in order to get more verbose log messages for each operation.

Note as well the purple module, a different approach, but might suit you:
http://kamailio.org/docs/modules/3.0.x/modules_k/purple.html

The old jabber module I developed is obsoleted, so nobody should rely on it.

Cheers,
Daniel
