A position is the fundamental geometry construct. The "coordinates"
member of a geometry object is composed of one position (in the case of a
Point geometry), an array of positions (LineString or MultiPoint
geometries), an array of arrays of positions (Polygons,
MultiLineStrings), or a multidimensional array of positions
(MultiPolygon).
A position is represented by an array of numbers. There must be at least
two elements, and may be more. The order of elements must follow x, y, z
order (easting, northing, altitude for coordinates in a projected
coordinate reference system, or longitude, latitude, altitude for
coordinates in a geographic coordinate reference system). Any number of
additional elements are allowed -- interpretation and meaning of
additional elements is beyond the scope of this specification.
