13     * DynAny objects can be created by invoking operations on the DynAnyFactory object.
14     * Generally there are only two ways to create a DynAny object:
15     * <UL>
16     * <LI>invoking an operation on an existing DynAny object
17     * <LI>invoking an operation on a DynAnyFactory object
18     * </UL>
19     * A constructed DynAny object supports operations that enable the creation of new DynAny
20     * objects encapsulating access to the value of some constituent.
21     * DynAny objects also support the copy operation for creating new DynAny objects.
22     * A reference to the DynAnyFactory object is obtained by calling ORB.resolve_initial_references()
23     * with the identifier parameter set to the string constant "DynAnyFactory".
24     * <P>Dynamic interpretation of an any usually involves creating a DynAny object using create_dyn_any()
25     * as the first step. Depending on the type of the any, the resulting DynAny object reference can be narrowed
26     * to a DynFixed, DynStruct, DynSequence, DynArray, DynUnion, DynEnum, or DynValue object reference.
27     * <P>Dynamic creation of an any involves creating a DynAny object using create_dyn_any_from_type_code(),
28     * passing the TypeCode associated with the value to be created. The returned reference is narrowed to one of
29     * the complex types, such as DynStruct, if appropriate. Then, the value can be initialized by means of
30     * invoking operations on the resulting object. Finally, the to_any operation can be invoked
31     * to create an any value from the constructed DynAny.
