[Tagging] Relation Junctions used for roundabouts

[Martin Vonwald]

Hi!

On the wiki page of junction=roundabout the Junctions proposal
(http://wiki.openstreetmap.org/wiki/Relations/Proposed/Junctions) is
mentioned and it is claimed, that we have to use a relation in case
the way of the roundabout is split up. Is this common practice?

Furthermore on that wiki page it states, that type=route and
route=junction for the relation should be specified, while on the
proposal page it says type=junction. Does anybody know what is
correct?

regards,
Martin
