Description

See nabble
http://camel.465427.n5.nabble.com/Changing-POJO-attribute-from-the-body-using-the-Simple-Expression-Language-tp5727971.html

We should have a script in the DSL

<route>
  ...
  <script>
    <groovy>some groovy stuff here</groovy>
  </script>
  ...
</script>

The script is then invoked and allows noop to avoid changing the message body.

Currently you can only do

<transform>
  <groovy> ... </groovy>
</transform>

... and that may change the message body with the return value from groovy.

With <script> you can avoid this.
