The tl:TLModelCache recognizes as relevant for its update behavior only tl:KnowledgeItem whose wrapper is a tl:TLModelPart. tl:KnowledgeAssociation are not considered further.
Suppose you have configured the model
in the application and then change the super type of C` from `B to A
then the TLModelCache does not update. This leads among other things to the fact that the attributes of C` are incorrectly still `Attr3 and Name.
