    initial v1  
    1 Note that this is the condition required for a set of Polygons to form a non-overlapping coverage, and for a set of LineStrings to form a non-crossing linear network.
     1This is a more general and useful test than `ST_Overlaps` (since `ST_Overlaps` does not detect the case when one geometry is covered by another, and it does not support mixed-dimension inputs).
     2
     3It is the condition required to determine if a set of Polygons forms a non-overlapping coverage, or if a set of LineStrings forms a non-crossing linear network.
