Question:
Global Context Broker Federation

Description:
Until now, I've been working with a context Broker Instance in stand-alone mode created in Fi-Lab/Cloud and using psb-orion-image. Now I would like to federate an instance of that CB with http//orion.lab.fi-ware.org. I use XML forms to create, update... and the name of the instance to federate is "UPCT:TEMPERATURE:SENSOR" wich sensor type is "UPCT:SENSOR".

So, connecting by SSH I send the next form:

(curl localhost:1026/NGSI10/subscribeContext s -S --header 'Content-Type: application/xml' -d @ | xmllint --format -) <<EOF
<?xml version="1.0"?>
<subscribeContextRequest>
<entityIdList>
<entityId type="UPCT:SENSOR" isPattern="false">
<id>UPCT:TEMPERATURE:SENSOR</id>
</entityId>
</entityIdList>
<reference>http://orion.lab.fi-ware.eu:1026/ngsi10/notifyContext&lt;/reference&gt;
<duration>P1M</duration>
<notifyConditions>
<notifyCondition>
<type>ONCHANGE</type>
<condValueList>
<condValue>temperature</condValue>
</condValueList>
</notifyCondition>
</notifyConditions>
<throttling>PT5S</throttling>
</subscribeContextRequest>
EOF

And I get a right reply, with and subscription ID. However, if I update de contextValue of my instance and try to send a query to http://orion.lab.fi.ware.eu:1026 I receive an error:

-:1: parser error : Start tag expected, '<' not found
Auth-token not found in request header
^

I think I should get the same value that I update to my Instance as indicate in

https://forge.fi-ware.org/plugins/mediawiki/wiki/fiware/index.php/Publish/Subscribe_Broker_-_Orion_Context_Broker_-_User_and_Programmers_Guide#Context_Broker_Federation

I need to know what's wrong and how could I do federete to the global CB.

Thank you
