I must appologise. Apparently I looked too quick on the changes you made at first and only saw the node named Bergaforsen. I missed that you've added rapid-information to the waterway-tagged way.

The node with a name might be maping for the renderer, but the information "amount" is the same as before, so I don't see this changeset as problematic any more.

I wish you luck with a better tagging scheme, both for canoeing and rapids.
