I'm trying to find a way to have amq topics automatically created with names taken from parts of the incoming message. I figured out a way to do that in DSL as follows:
from("jbi:endpoint:http://servicemix.apache.org/mycorp/camel-router/endpoint").recipientList(xquery("concat('activemq:topic:dynamicTopics/topic.',//Sample/Xquery/Expression[@PartyType=1]/@FacilityCode)").asString());

This works fine and topics are created correctly named as follows

If say, FacilityCode is "NYC", the topic will be created as:

dynamicTopics/topic.NYC

The problem arises when trying to do this in XML config. Given the following XML config file snippet:

<camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring">
<route>
<from uri="jbi:endpoint:http://servicemix.apache.org/mycorp/camel-router/endpoint"/>
<recipientList>
<xquery>concat('activemq:topic:dynamicTopics/topic.',/,//Sample/Xquery/Expression[@PartyType=1]/@FacilityCode)</xquery>
</recipientList>
</route>
</camelContext>

Yields the following error when passing a message through the router:
