 For example, `1 > b` and `1 < b` are both false when b is NaN.
 * String values are compared for ordering using lexicographic order (e.g. `"x" < "xy"`).
 * Boolean values are compared for ordering such that `false < true`.
-* *Comparison* of spatial values:
- ** Point values can only be compared within the same Coordinate Reference System (CRS) -- otherwise, the result will be `null`.
- ** For two points `a` and `b` within the same CRS, `a` is considered to be greater than `b` if `a.x > b.x` and `a.y > b.y` (and `a.z > b.z` for 3D points).
- ** `a` is considered less than `b` if `a.x < b.x` and `a.y < b.y` (and `a.z < b.z` for 3D points).
- ** If none if the above is true, the points are considered incomparable and any comparison operator between them will return `null`.
+* Spatial values cannot be compared using the operators `<`, `+<=+`, `>`, or `>=`.
+To compare spatial values within a specific range, use either the xref:functions/spatial.adoc#functions-withinBBox[`point.withinBBox()`] or the xref:functions/spatial.adoc#functions-point-wgs84-2d[`point()`] function.

 * *Ordering* of spatial values:
  ** `ORDER BY` requires all values to be orderable.
  ** Points are ordered after arrays and before temporal types.
