 <xs:documentation>A unitless quantity is a quantity which has no unit of measure symbol, but could be a real physical measurement. Examples would be a count, pH, wire gauge (AWG and BWG) and shoe size. This is different from a dimensionless quantity which represents a ratio whose units of measure have cancelled each other. DImensionless quantities can have units of measure (like ppm or %) or may not have a displayable unit of measure symbol (in which case the units symbol Euc is used in a data transfer). Units derived from a unitless number simply ignore the unitless part. For example, the unit for counts per hour is just inverse hours (1/hr).</xs:documentation>
