11   * Direct implementations of ObjectModelProvider interface can be thought of as "typed" providers in a sense that
12   * arguments of <code>getChildren</code>, <code>getElementValue</code> and <code>getAttributeValue</code> methods
13   * are supposed to be of concrete Java types (other than <code>java.lang.Object</code>) from the target class hierarchy.
14   * Contrary, in GenericObjectModelFactory these arguments are of type <code>java.lang.Object</code>.
15   * The framework won't introspect an implementation of GenericObjectModelProvider to find "typed" implementations of
16   * <code>getChildren</code>, <code>getElementValue</code> and <code>getAttributeValue</code>.
17   * Instead it will call the generic methods.
