allows you to write a subquery and leverage the spatial filter in a custom way. So, if you wished to override the geom && and do ST_Intersects instead then you could do (in XML):<Parameter name="table">(Select * from mytable where ST_Intersects(geom,!bbox!)) as mysubquery</...

When used to define a custom relationship, it can have (T, F, *, 0, 1, or 2) in each of the nine cell slots. When used to output the most constraining relationship between predefined geometries A and B, it can contain only F, 0, 1, or 2 in the cell slots. The reason for ...
