           * call or through some other means external to this specification.
           * Providers of get_allValidValues Web services that serve multiple
           * registries and providers that restrict who can use their service may
           * require authInfo for this API.
           * @param modelKey A required uddiKey value that identifies the specific
           * instance of the tModel which describes the value set or category
           * group system for which a Web service to get all valid values has been
           * provided. It uniquely identifies the category, identifier, or
           * category group system for which valid values are being requested.
           * @param chunkToken Optional element used to retrieve subsequent groups
           * of data when the first invocation of this API indicates more data is
           * available. This occurs when a chunkToken is returned whose value is
           * not "0" in the validValuesList structure described in the next
           * section. To retrieve the next chunk of data, the chunkToken returned
           * should be used as an argument to the next invocation of this API.
           * @param validValue A validValuesList structure is returned containing
           * the set of valid values for the external category or identifier
           * system. The list MUST contain a chunkToken if the Web service
           * provider wishes to provide the data in packets.
