Configuring syslogd-configuration.xml to only listen on TCP, anyone know the syntax?

Is there a correct syntax of syslogd-configuration.xml for tcp protocol, something like the / / marked statemen below?

<?xml version="1.0"?>
<syslogd-configuration>
    <!--
      optional attribute "timezone":
          - if set it will be used as default timezone if no timezone is given
          - if not set the system time zone will be used
    -->
    <configuration
            syslog-port="10514"
 /           ip-protocol="TCP"/
            new-suspect-on-message="false"
            parser="org.opennms.netmgt.syslogd.RadixTreeSyslogParser"
            forwarding-regexp="^.*(local3).*$"
            matching-group-host="6"
            matching-group-message="8"
            discard-uei="DISCARD-MATCHING-MESSAGES"
            timezone="UTC"
            />

Kind Regards

As far as I am aware, there is no support for syslog over TCP in OpenNMS.
