Activate client sessions once resource binding has been done. Clients need to active their
sessions in order to engage in instant messaging and presence activities. The server may
deny sessions activations if the max number of sessions in the server has been reached or
if a user does not have permissions to create sessions.<p>

Current implementation does not check any of the above conditions. However, future versions
may add support for those checkings.
