Question:
Fiware IoT Broker and IoT Configuration Manager XML Validation

Description:
I figured out I had to have another GE, the IoT Configuration Manager working parallel to the IoT Broker in order to manage the entities from which we will get data. Now, it seems that the XMLValidator code is giving me some trouble. I registered an entity via HTTP POST osgi9 directly with the configuration manager. Then I try to access it by communicating via osgi10 with the IoT broker. The IoT Broker communicates with the IoT DIscovery service and gets a response, but then the XMLValidator says the XML is wrong even tough it clearly is not.

This is the IoT Broker asking for the availability of a resource to the IoT ConfMan:

2014-11-27 10:31:13,682 | INFO | (HttpConnectionClient.java:initializeConnection:170) | Output

Stream: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<discoverContextAvailabilityRequest>
<entityIdList>
<entityId isPattern="false">
<id>Dorm</id>
</entityId>
</entityIdList>
<attributeList/>
<restriction>
<scope>
<operationScope>
<scopeType>IncludeAssociations</scopeType>
<scopeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:string">SOURCES</scopeValue></operationScope>
</scope>
</restriction>
</discoverContextAvailabilityRequest>

Then IoT Broker gets:

2014-11-27 10:31:13,947 | INFO | (HttpConnectionClient.java:initializeConnection:188) |

It is clearly seen by the received xml that at least the providingApplication is received but XMLValidator is not seeing this.
