Willem Jiang resolved CAMEL-5550.
---------------------------------
Resolution: Fixed
Applied patch into trunk with thanks to Alan.
As there are big gap between the Scala DSL and Java DSL. I think we should
create another JIRA for it.

> We recently added headerName to @XPath / @XQuery to support doing xpaths on
> headers. We should add that as well to the xpath/xquery languages so its
> exposed in the DSL, so people can use that.
> For example in a content based router. Today there is some functions that
> return a header, but its a bit cumbersome to use. Maybe people have stored a
> xml in a header, and just want the xpath to evaluate on that.
> The Java / Scala DSL is a bit heavier to add, as it would entail new methods
> in various builder classes to support that. And we got a bunch already for
> the namespaces, and return type etc. So be selective and only add a few for
> the header which makes the most sense. People can always create the
> expression/predicate using the xpath builder itself.
