No, I discussed it with a few people on the OSM IRC channel but other
than that, I believe our mailing list knows as much about it as anyone.

The node is required but it doesn't have to have a role. The
requirements are that the relation has two members that are ways that
meet at the specified node. None of them need to have roles.

It was originally suggested that the node had role "junction" but I
don't see why that is required.

Cheers,

Mark
