For the X values only, xmin may be greater than xmax, in which case an object in this bounding box may match if it contains an X such that `x >= xmin` OR`x <= xmax`. In geographic terminology, the concepts of `xmin`, `xmax`, `ymin`, and `ymax` are also known as `westernmost`, `easternmost`, `southernmost` and `northernmost`, respectively. For `geography` types, these points are further restricted to the canonical ranges of [-180 180] for X and [-90 90] for Y. +For geometry and geography types, lower_bounds and upper_bounds are both points of the following coordinates X, Y, Z, and M (see Appendix G) which are the lower / upper bound of all objects in the file.
