I will add support for better visualizing two ways which are on top of
each other.

However, I don't see a reason to try to forbid any doubled way creation.
Ways are logical information and I can think of numerous situations where
two ways should be consist of exactly the same line segments. This is a
feature, not a bug! ;-)

Line segments are physical representations of the world, not logical.
Since there can only be one physical line between two points, I don't see
a reason why someone would want to create two line segments on top of each

But I could allow it, if it is requested ;-). I don't think the server
prevent doubled line segments.

Deleted ways should definetly not appear in the xml document at all. Steve?

Ciao, Imi.
