                    | boreholeLength | Quantity |  | The distance along a borehole.
-- Description --
This will be determined by the data provider (ie, "length" can have different sources, like drillers measurement, loggers measurement, survey). | 
                
                    | elevation | DirectPosition |  | The vertical height above datum of the borehole collar.
-- Description --
This is a compromise approach to supply elevation explictly for location; this is to allow for software that cannot process 3-D GM_Point. Use null if elevation is unknown. Direct position shall have a dimension of 1, and CRS will be a "vertical" CRS (e.g. EPSG CRSs in the range 5600-5799). | 
                
                    | location | GM_Point |  | The location of the borehole collar. | 
                
                    | purpose | BoreholePurposeValue |  | The purpose for which the borehole was drilled.
-- Description --
EXAMPLE: site investigation, mineral exploration, hydrocarbon exploration, water resources. |
