[OSM-dev] multipolygon relation and non-closed ways

[Pedro Larroy]

The point I wanted to make is that when encoding riverbanks with a
multipolygon relation in which the ways are parts of the riverbank
such as http://www.openstreetmap.org/browse/way/75367154  contradicts
the definition of multipolygon relation
http://wiki.openstreetmap.org/wiki/Relation:multipolygon  which says
that member ways are closed.

I see that these ways have to be stitched toghether to form a propper
closed polygon.

Perhaps a new relation type would be better?

Pedro.
