In this task, you add a node to the template for a generic element that is not from All Metaclasses. If you want only elements from a specific part of the model, such as the Package, rather than all elements in the model. In this task, you build a series of iterations that creates a path to the generic element.
To extract all classes in the package:
The nodes you just added instruct IBM® Rational® Rhapsody® ReporterPLUS to iterate through the model to find the project, then iterate through the containedPackages and extract all the classes. The labels that are added to the template view identify what the nodes do and what part of the model they are from.
