How to set 'MODE' in <dataformat> with Bluprint DSL ?

Issue

• We cant see how its possible to set the 'Mode' on xStream via the blueprint/java DSL. If it is, can you point me in the right direction ?

• If not, is it possible for this to be added ?
  i.e.: new property on:
  https://github.com/apache/camel/blob/master/components/camel-xstream/src/main/java/org/apache/camel/dataformat/xstream/AbstractXStreamWrapper.java

• So we can do:

<dataFormats>
   <xstream driverRef="jsonDriver" encoding="UTF-8" id="jsonConverter" mode="NO_REFERENCES"></xstream>
</dataFormats>

• The 'Mode' can be set with Java DSL as below,

public void setMode(String mode) {
                if ("NO_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.NO_REFERENCES;
                } else if ("ID_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.ID_REFERENCES;
                } else if ("XPATH_RELATIVE_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.XPATH_RELATIVE_REFERENCES;
                } else if ("XPATH_ABSOLUTE_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.XPATH_ABSOLUTE_REFERENCES;
                } else if ("SINGLE_NODE_XPATH_RELATIVE_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.SINGLE_NODE_XPATH_RELATIVE_REFERENCES;
                } else if ("SINGLE_NODE_XPATH_ABSOLUTE_REFERENCES".equalsIgnoreCase(mode)) {
                        this.mode = XStream.SINGLE_NODE_XPATH_ABSOLUTE_REFERENCES;
                }
        }

• But with blueprint, there no 'Mode' parameter called as in the Java DSL using the camel-xstream component,

<bean id="jsonDriver"
class="com.redhat.sample.xstream.io.json.JsonHierarchicalStreamDriver"></bean>

<camelContext id="camel" xmlns=";;
  <dataFormats>
    <xstream id="xstream" driverRef="jsonDriver"></xstream>            
  </dataFormats>

  <route>
    <from uri="direct:start"></from>
    <marshal ref="xstream"></marshal>
    <to uri="mock:result"></to>
    </route>
</camelContext>
