Class If true, the Classifier does not provide a complete declaration and can
typically not be instantiated. An abstract classifier is intended to be
used by other classifiers e.g. as the target of general metarelationships
or generalization relationships.

isLeaf : Boolean (1 1); -- source
RedefinableElement Indicates whether it is possible to further redefine a RedefinableElement.
If the value is true, then it is not possible to further redefine the RedefinableElement.
Note that this property is preserved through package merge operations;
that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false)
must be preserved in the resulting RedefinableElement of a package merge
operation where a RedefinableElement with isLeaf=false is merged with a
matching RedefinableElement with isLeaf=true: the resulting RedefinableElement
will have isLeaf=false. Default value is false.
Default value: FALSE
