You don't include dependencies. The route is the route and only the route.
Provided you make sure all the dependencies are available, either on DLS, your own web site, or elsewhere, it will be fine. If any dependencies are difficult to find then you might need to add a note in the description saying where they are.
However, I think you might need to acknowledge the dependencies' creators somehow. I don't know if this is just being polite or actually a requirement. Nor do I know for sure how it's done. Perhaps someone else could explain that aspect.
