            <documentation>Enumeration of Energistics quantity classes from the Unit of Measure Dictionary. Each quantity class represents a physical dimension or dimensionless ratio that can be measured. The quantity class defines what is being measured (e.g., length, pressure, volume per time), while units within that class define how it is measured (e.g., metres, feet, inches for length). This enumeration provides a comprehensive list of all standard quantity classes defined in the Energistics Unit Dictionary, including fundamental SI quantities, derived quantities, dimensionless ratios, and specialized petroleum/geotechnical quantities.</documentation>

These quantity classes represent physical dimensions or dimensionless ratios specific to geotechnical, geoenvironmental, and related engineering applications that are not included in the standard Energistics dictionary. Each quantity class defines what is being measured (the physical dimension), while units within that class define how it is measured. These extensions are necessary to support specialized measurements in soil mechanics, rock mechanics, groundwater analysis, geophysical testing, and materials characterization common in geotechnical practice.</documentation>
