UTP11 — Figure 6.19 need clarification

In section 6.6.1 Money Example, Figure 6.19 shows a generalization relationship between IMoney and Money/MoneyBag.

The prefix "I" supposes the IMoney classifier to be an interface. If so, the generalization relationship is wrongly used. Instead, this should rather be a InterfaceRealization (dashed arrow).

But if so IMoney classifier is supposed to be a class, the prefix "I" should removed. This would require the class to be renamed, to avoid name clashes with the specialized class "Money".

Agreed, the relationship must be an InterfaceRealization
