-- Name -- Vertical extent type -- Definition -- Vertical dimensional property consisting of an absolute measure or range of measures referenced to a well-defined vertical reference level which is commonly taken as origin (ground level, mean sea level, etc.).
-- Name -- Vertical extent range type -- Definition -- Value indicating the upper and lower bounds of the height/depth range. -- Description -- In the case of depth, the range between the deepest (lower bound) and most shallow (upper bound) aspect of the deposit body, where the depth is true vertical depth below a chosen vertical reference level.
-- Name -- Renewable and waste value -- Definition -- Types of renewable and waste resources. -- Description -- NOTE Waste values have been included in this code list to simplify the code lists rather than to imply that only renewable waste is included.
-- Name -- Classification and quantification framework value -- Definition -- Values for the most widely used classification schemes to classify and quantify energy resources. -- Description -- NOTE Most of the listed classification frameworks only focus on fossil fuels.
-- Name -- Vertical reference value -- Definition -- Values indicating the reference level of the vertical extent.
-- Name -- Fossil fuel class value -- Definition -- Different sublevels within a resource for distinguishing real from potential or expected amount of fossil fuel resources.
-- Name -- Vertical extent value -- Definition -- Either a single number or a range of height/depth values to describe the height/depth position of an Energy Resource.
