they may be the Interfaces that are provided by its public Ports.

NamedElementA name that allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
Namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.
