          <value xml:lang="en">
            Specifies the unit associated with a metric concept.
            Example:
              <![CDATA[<concept id="area_unit" extends="unit:unit">
                <info>
                  <name>
                    <value>Area in square kilometers</value>
                  </name>
                </info>
                <table ref="area_unit_table"/>
              </concept>]]>
            The table contains a single row that contains the property values:
              symbol,symbol_position,unit_text
              km²,END,square kilometers
            One can then use this unit in defining a metric concept:
              <![CDATA[<concept id="country_area" extends="quantity:magnitude">
                <info>
                  <name>
