Port References the interfaces specifying the set of operations and receptions
that the classifier expects its environment to handle via this port. This
association is derived according to the value of isConjugated. If isConjugated
is false, required is derived as the union of the sets of interfaces used
by the type of the port and its supertypes. If isConjugated is true, it
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.

Constraints:
Signature: port_destroyed() : Boolean;
Description: When a port is destroyed, all connectors attached to this port will be
destroyed also.
Expression: true
Signature: port_aggregation() : Boolean;
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
Operations:
No additional operations.
