UML14 — description of Component on page 137

The description of Component on page 137 says that the provided and required
interface associations are derived both directly, from implement and use
dependencies, and from realizing classifiers and owned ports. What isn't
clear to me is whether the cup and ball notation can be used for all
provided and required interfaces, or just for those directly implemented and
used. If it can be used for all then it isn't clear whether you can
distinguish between direct and derived interfaces. However, I note on Figure
89 that /orderedItem is preceded by a slash - is that how the difference is
notated?
