Class: QuantityValue
Description: A value of an attribute that is quantitative and measurable, expressed as a combination of a unit, (optional) unit prefix and a numeric value. An optional binary relation qualifier may also be given, to allow capture of relative values, e.g., <1000.0 nM meaning "less than 1000 nanometers"
