                A variant element is closely analogous to a resource element in the IMS CP informaton mod-

                to assets that are all of the same type or different types i.e. file formats. The Variant 
                class points to the alternative resource. Metadata is used to describe the nature of a co-
                llection of alternative assets and their intended use. Examples include, but are not limi-
