SwitchYard endpoints don't work with Camel 'enrich' EIP

Issue

Use of a SwitchYard dsl will fail in a Camel EIP implementation. Example follows.

<?xml version="1.0" encoding="ASCII"?>
<routes xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="switchyard://EnrichRoute2"/>
    <log message="EnrichRoute2 - message received: ${body}"/>
    <!--  'to' works in the next line, 'enrich' does not -->
    <to uri="switchyard://Enrich" />
    <log message="EnrichRoute2 - after : ${body}"/>
  </route>
</routes>
