Yes you can. The DSL has special support for that so it makes
converting from java <-> xml easier.
But you should not have ${ } etc just do as you would do in Java DSL
<camel:setHeader headerName="Exchange.FILE_NAME">
When a key starts with Exchange. then Camel checks if its a field from
the Exchange interface and uses its value.

And btw use simple instead of constant. As constant is really just a
hardcoded fixed constant value. So if you want the current date, use
the simple language that has this function.
