Answer Posted / paul howard
Composition can be used to model by-value aggregation which
is semantically equivalent to an attribute. In fact
composition was originally called aggregation-by-value in an
earlier UML draft with “normal” aggregation being thought of
as aggregation-by-reference. The definitions have changed
slightly but the general ideas still apply. The distinction
between aggregation and composition is more of a design
concept and is not usually relevant during analysis.
