0029  * to handle this.
0030  *
0031  * It can also be used as a base for more complex models with their own built-in
0032  * proxy. In some case it can be preferable over implementing a GeometryAdapter.
0033  * For example if the proxy already exists or has tightly coupled interaction
0034  * with more roles (or filters).
