Again, my GML expert friend says that a polygon would look like:
<gml:Polygon>
<gml:exterior>
<gml:LinearRing>
<gml:pos>12 4</gml:pos> <gml:pos>12 8</gml:pos> ...
</gml:LinearRing>
</gml:exterior>
</gml:Polygon>
The rigorous geometry model carefully distinguishes between the interior
and the perimeter of the object. This is useful in cases where
you really do want to indicate that a specific sub-area is *excluded*
from
consideration.
