[josm-dev] Validator: Unordered coastline

[Matthias Julius]

Validator just gave me an "Unordered coastline" error and highlighting
the last node for a coastline I had been working on.  What does that
mean?

The notion of unordered ways made sense when we still had segments.
But how can a simple list of nodes be unordered?

This error is not listed on
http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Validator#Validations
Is there another source of information about validator checks besides
"Read the Source, Luke!"?
