Fwd'd message below ... makes sense to me that roundabout is always linear, but documentation is ambiguous....
Any ideas about this issue?

Thanks for the opportunity to ask you some (more general) questions
directly. I’ll promise to keep them short and focused on getting a
general understanding of OSM and some of its inherent functionality. The
technical questions will go to the dev list.
In looking at some features I am a little puzzled as to when
a way is an “area” and when it is not and how to resolved the “conflict”.
For example “junction=roundabout”
seems to a linear feature even though the way is “closed” –
loops back on itself. The previous link lists the feature as linear vs.
the table at http://wiki.openstreetmap.org/wiki/Map_Features#Highway indicating that the feature can be both linear and polygonal.
A similar situation arises from “highway=platform”
which could be all three type (according to the table at http://wiki.openstreetmap.org/wiki/Map_Features#Highway)
Could you clarify this situation for me?
