Claus Ibsen commented on CAMEL-3564:
------------------------------------
>From a tooling perspective and maybe also as an end user, you would maybe
>better be able to figure out how to refer to a bean if we had a
{code:xml}
<ref>foo</ref>
{code}
element as an expression. Then it's listed in the XSD schema and the editor can
show it for you.
Also we can list it at the website, as we do with the others
http://camel.apache.org/languages
I am not sure that a new user would be able to understand he can use the simple
expression language to resolve his issue?
We could of course add a FAQ entry and have an example, that would help some
users.
That said, I would think from a tooling perspective that the {{<ref>}} element
would help there as well.
I think we should re-consider this for Camel 2.7.

> This is needed for folks using XML routing. An expression which can refer to
> something from the registry.
> We can also add a {{ref}} function to the simple language so you can use that
> as well.
> In simple the function should be {{ref:id}} where id is the id to lookup.
> For example
> {code:xml}
> <bean id="foo" class=...>
> <!-- options -->
> </bean>
> <setProperty name="myFoo">
> <ref id="foo"/>
> </setProperty>
> {code}
> And when using simple
> {code:xml}
> <setProperty name="myFoo">
> <simple>${ref:foo}</simple>
> </setProperty>
> {code}
