It's common to do in YAML syntax:

steps:
- marshal:
    json: {}

But the marshaller dependency is not recognized automatically and "camel-jackson" needs to be explicitly added (e.g. using -d). The language inspector can do it automatically.

This needs an exclusion mechanism as well.

for instance

<setBody id="setBody10">
--
<constant>
<![CDATA[
<v1:isAliveResponse xmlns:v1="http://model.ws.xxxx.com/global/v1">
<isAlive>true</isAlive>
</v1:isAliveResponse>
]]>
</constant>
</setBody>
