How can I send addicional info from ocs client to ocs server ..?

I want to populate aditional information from OCS client to  OCS server.

The idea is that I out some XML file with this content:

----------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>
<ACCOUNTINFO>
        <KEYNAME>Responsable</KEYNAME>
        <KEYVALUE>Infraestructura</KEYVALUE>
</ACCOUNTINFO>

------------------------------------------------------------------------------------

And send it information to OCS server..

Is it possible...?
