Adding custom XML in subscription request

Hi,

I desperately need a way to attach additional XML when a user subscribes to another user.

For example, the standard method to subscribe to a user is as follows…

<presence to="username@server.com" type="subscribe>

..username@server.com recieves the following…

** **

** **

** **

I’ve been trying all day to try and attach additional information, such as…

or…

** true**

But the user who recieves the subscription request always recieves the same XML.

Anyone got any ideas? Any help would be much appreciated.

Chris
