Rather than use a high-level specification approach, it is intended that programmers use the classes directly to compose interfaces, although the possibility of developing code-generators for building (parts of) interfaces is not excluded. The toolkit supports dynamic construction and re-configuration of interfaces and adopts a very flexible approach to interfacing with underlying applications.
