|For Standard||ECOM2 v2.0|
These types represent numeric quantities with a unit of measure implemented as a uom attribute. The units are gathered into single quantity classes, which represent a group of units. The unit symbols appropriate for the class are captured as enumerated lists. The implementation of this is to develop a type for each uom class that is a union of a standard list, the unknown value, and the Other: extension. Additional files will contain these structures.
