The Rest DSL supports automatic binding json/xml contents to/from 
POJOs using Camels Data Format.
By default the binding mode is off, meaning there is no automatic 
binding happening for incoming and outgoing messages.
You may want to use binding if you develop POJOs that maps to 
your REST services request and response types.
