Object Part Specification hasNumberOfParts Part Cardinality

Part Cardinality isPartCardinalityFor Object Part Specification

This specifies how many of a particular part should be in an
instantiated composite type.  For example, when a type of car is
instantiated, it should have four wheels.

Any relations to part specification will be replicated for each of the
parts filling that specification in the instantiated composite.  For
example, if we have a object part specification for the front wheels,
with part cardinality of two, then any connections, like one from the
engine, will be instantiated for both wheels.
