UML22 — Element and Comment in Basic

The definition of the classes Element and Comment in the Basic package is ambiguous. The Basic package
imports Abstractions::Elements::Element and Abstractions::Comments::Comment. An inheritance
relationship and an Association called ownedComment is introduced between Element and Comment in the
package Basic. However, these relationships were already defined for these classes in the package
Abstractions (see the top two diagrams in Figure 4). Therefore, the complete model of Element and
Comment in the Basic package is the model shown in Figure 4, clearly showing a redundant association
called ownedComment, and a redundant inheritance relationship between Abstractions::Elements::Element
and Comment.
