The system doesn't know anything about any of them, they're all handled the same. It's merely a question of what's built in and what's not. "Custom" just means "not built in". It walks the list and whatever happens to generate a viable result is used, in whatever order it finds them, whether it's a ref to a built-in bean or a bean that's supplied by a user.
