      A unit of money used to express value, with an ISO 4217 code. Values are
      keyed by the lowercase alphabetic code. Starter subset: three
      currencies. No alias is a bare word or symbol that several currencies
      share ("dollar", "$"): the US dollar is "US dollar", "US dollars" or
      "US$", so another dollar can be added without a collision.

      An amount of money. It is only meaningful together with its currency:
      its unit is one of the values of currency, so a concept that extends it
      states the currency as that value (unit: USD), and the check resolves
      the unit to exactly one currency. A dataset that does not store the
      currency must still say which one applies.
