UML22 — Section: 17.1

In fig. 412 the PrimitiveTypes package is sitting alone with no dependencies or navigation lines yet it is on the same level as Kernal, BasicActivities, BasicInteractions, and InternalStructures. If all of the other packages don't import elements from PrimitiveTypes, I would suggest offsetting the PrimitiveTypes package or putting it in a separate figure. Question - Why not develop PrimitiveTypes as an enumeration with Boolean, Integer, String, UnlimitedNatural, and UserDefinedKind or UserDefinedList as the elements of the enumeration?
