        Only features that have a geometry that intersects the bounding box are

        selected.  The bounding box is provided as four or six numbers,

        depending on whether the coordinate reference system includes a

        vertical axis (height or depth):


        * Lower left corner, coordinate axis 1

        * Lower left corner, coordinate axis 2

        * Minimum value, coordinate axis 3 (optional)

        * Upper right corner, coordinate axis 1

        * Upper right corner, coordinate axis 2

        * Maximum value, coordinate axis 3 (optional)


        If the value consists of four numbers, the coordinate reference system

        is WGS 84 longitude/latitude (http://www.opengis.net/def/crs/OGC/1.3/

        CRS84) unless a different coordinate reference system is specified in

        the parameter `bbox-crs`.


        If the value consists of six numbers, the coordinate reference system

        is WGS 84 longitude/latitude/ellipsoidal height (http://www.opengis.

        net/def/crs/OGC/0/CRS84h) unless a different coordinate reference

        system is specified in the parameter `bbox-crs`.


        The query parameter `bbox-crs` is specified in

        OGC API - Features - Part 2: Coordinate Reference Systems by Reference.


        For WGS 84 longitude/latitude the values are in most cases the sequence

        of minimum longitude, minimum latitude, maximum longitude and maximum

        latitude.  However, in cases where the box spans the antimeridian the

        first value (west-most box edge) is larger than the third value

        (east-most box edge).


        If the vertical axis is included, the third and the sixth number are the

        bottom and the top of the 3-dimensional bounding box.


        If a feature has multiple spatial geometry properties, it is the

        decision of the server whether only a single spatial geometry property

        is used to determine the extent or all relevant geometries.'
