A SpatialSegment is aiming to localise any meaningful content in a spatial document (mainly Image). For example, one can think to
a picture showing some people. Specific segment can be localised with coordinate descriptors defining the silhouettes of each person
in the picture. Then, specific annotations can be applied to each segment (i.e. to declare that those are human beings). It is the
kind of segment that may be used for image and video unit. When there are only two coordinates associated to the spatialSegment,
it means that the shape is a disk. The first coordinate is the centre and the second one is one point of the circle. Otherwise,
coordinates are describing a closed shape since the last coordinate of the list will be linked to the first one.
