Insert an alert as an Oracle Service Bus customization file

I am creating a customization file for OSB, and I would need to add an alert in this, so whenever it is loaded, the affected resources are modified to include those alerts.

So far I have followed instructions explained in See Example - Adding and Deleting SLA Alert Rules. I have created a customization file with the same structure than the example (actions - add - value), just changing the value for the alert or even using the one shown in the example.

Anyway, when I try to apply this customization file on OSB, I always get the error:
org.apache.xmlbeans.impl.values.XmlAnyTypeImpl cannot be cast to com.oracle.xmlns.servicebus.monitoring.alert.AlertRuleDocument

My customization file is:

<?xml version="1.0" encoding="UTF-8"?>

            </xt:value>
        </xt:add>
    </cus:actions>
</cus:customization>
</cus:Customizations>

Does anyone know how to solve this or maybe I am doing something unproperly?

Thanks for your help.

Solution

Finally I made work a customization file with an alert like this:

<?xml version="1.0" encoding="UTF-8"?>
<cus:Customizations xmlns:cus="http://www.bea.com/wli/config/customizations" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xt="http://www.bea.com/wli/config/xmltypes" xmlns:aler="http://xmlns.oracle.com/servicebus/monitoring/alert">

            <xt:refsToSearch xsi:type="xt:LocationRefType">
                <xt:type>Folder</xt:type>

            </xt:refsToSearch>                                                       
        </xt:ownerQuery>
    </cus:owners>
    <cus:actions>
        <xt:replace>
            <xt:envValueType>Service SLA Alert Rule List</xt:envValueType>
            <xt:value>

                        <aler:condition aggregation-interval="10">

                            </con1:monCondExpr>
                        </aler:condition>
                        <aler:alertDestination ref="bus_ver/AlertaProva"/>
                    </aler:alertRule>
                </aler:alertRules>
            </xt:value>
        </xt:replace>
    </cus:actions>
</cus:customization>

Main differences that provoked error in initial XML:

xmlns:aler="http://xmlns.oracle.com/servicebus/monitoring/alert" -> OK vs xmlns:aler="http://www.bea.com/wli/monitoring/alert" -> KO
Service SLA Alert Rule List -> OK vs Service SLA Alert Rule -> KO
