What is true about the use of a Template Classifier to specify the Type of a Typed Element?
A . The Template Classifier needs to be modeled
B . The Template Classifier must have defaults for all of its Template Parameters
C . The Type Property of the Typed Element must directly name the Template Classifier.
D . Template Classifiers cannot be used in the specification of Types for Typed Elements.
E . A set of bound elements provides values for the Template Parameters of the Template Classifier.

Answer: E

Explanation:

When a template classifier is used to specify the type of a typed element, the actual parameters for the template classifier’s formal parameters must be provided by a set of bound elements. This means that for a template classifier to be used as a type, there must be a corresponding binding that specifies what elements are used as arguments for its template parameters. This allows the typed element to have a concrete type that is a specific instantiation of the template classifier with particular values for its template parameters. This use of template classifiers is described in the UML 2.x Superstructure Specification, which details how template binding works to create specific instances of template classifiers.
