I really don't like storing info like this in an attribute -- I think it
should be another variable, instead. it is a bit tricky with "nested" data
like this, but yu can link variables together with something like:
int SOMETHING(station); // number of polygons in each collection
SOMETHING:node_coordinates="lon lat";
SOMETHING:geometry_type="multipolygon";
SOMETHING:node_count="node_count_1"
int node_count_1(num_nodes);
...
data
node_count_1 = 4, 3, 3, 3, 5, 3, 3;
Thus I

I think we should come up with a better name here -- it would help be parse
it anyway :-)
