   Hi I'm trying to use xml based route using routes. I've a xpath expression 
which uses namespace and it's not taking defined namespaces in routes xml. How 
do I define namespaces? Here is my route xml
   
   ```xml
   <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
           xmlns="http://camel.apache.org/schema/spring";
           xmlns:soap-env="http://www.w3.org/2003/05/soap-envelope";
           xsi:schemaLocation="
               http://camel.apache.org/schema/spring
               http://camel.apache.org/schema/spring/camel-spring-3.4.2.xsd";>
       <route id="myroute">
           <from uri="platform-http:/handler?httpMethodRestrict=POST"/>
           <setProperty name="MessageType">
               <xpath resultType="java.lang.String" logNamespaces="true">
                   local-name(/soap-env:Envelope/soap-env:Body/*[1])
               </xpath>
           </setProperty>
           <log message="${exchangeProperty.MessageType}"/>
           <setBody>
               <simple>
                   Hello ${body}
               </simple>
           </setBody>
       </route>
   </routes>
   ```
   
   When I try to post XML file to handler endpoint I get the following error:
   
   ```java
   org.apache.camel.language.xpath.InvalidXPathException: Invalid xpath: 
local-name(/soap-env:Envelope/soap-env:Body/*[1]). Reason:

   Can anyone point me how to define custom namespaces?
