Best way for reusing routes

Hi all,

I'd like to write couple of route definitions that will be reused in
multiple places.

If I use the Java DSL it is straight forward, I can reuse the RouteBuilder
class in many places, but I want to use the XML DSL and I can see two
options:

1. Use <routes> statements. Looks like it is mostly used for unit tests.
2. Use routeContext to define the routes.

Can anyone tell me what is the difference and the intended use of 1 and 2?

What limitations they have compared to normal routes defined in Java DSL or
XML DSL?
