Overview

Basic type for specifying monetary amounts. A double value (e.g.,
1.00 or 1.0) is meaningful as a monetary amount when accompanied by a
specification of the currency, in which case the value specifies
the amount in that currency. An AmountType expresses both the value
(a double) and the currency. Details such as prices, fees, costs,
and payments are specified as amount types.
