Port References the interfaces specifying the set of operations and receptions
that the classifier offers to its environment via this port, and which
it will handle either directly or by forwarding it to a part of its internal
structure. This association is derived according to the value of isConjugated.
If isConjugated is false, provided is derived as the union of the sets
of interfaces realized by the type of the port and its supertypes, or directly
from the type of the port if the port is typed by an interface. If isConjugated
is true, it is derived as the union of the sets of interfaces used by the
type of the port and its supertypes.

Description: Port.aggregation must be composite.
Expression: true
Signature: default_value() : Boolean;
Description: A defaultValue for port cannot be specified when the type of the Port is
an Interface
Expression: true
