AbstractionAn composition of an Expression that states the abstraction relationship
between the supplier and the client. In some cases, such as Derivation,
it is usually formal and unidirectional; in other cases, such as Trace,
it is usually informal and bidirectional. The mapping expression is optional
and may be omitted if the precise relationship between the elements is
not specified.
