[OSM-talk] The segments vs ways vs superways question again...

[David Earl]

If the structure is changed, would it make sense at the same time to
explicitly represent areas rather than relying on tags to imply this
(consider the difference between natural=water and junction=roundabout
applied currently to a colection of ways): an area would be a collection of
nodes where the last is defined to close with the first.

<area ...>
  <tag k='natural' v='water' />
  <tag k='name' v='Mill Pond' />
  <noderef id='...' />
  <noderef id='...' />
  <noderef id='...' />
  ...
</area>
