     * @struct Struct_Field
     *
     * @brief Name/type pair for fields of an OMG IDL defined
     *        structure or exception.
     *
     * A @c Struct_Field contains the corresponding name and pointer
     * to the @c CORBA::TypeCode for a given OMG IDL defined type.
     * For example, the fields in following OMG IDL structure:
     *
     * \code
     *   struct Foo
     *   {
     *     long   the_number;
     *     string the_string;
     *   };
     * \endcode
     *
     * would be represented using the following statically instantiated
     * @c TAO::TypeCode::Struct_Field array:
     *
     * \code
     *   TAO::TypeCode::Struct_Field<char const *> _tao_fields_Foo[] =
     *     {
     *       { "the_number", &CORBA::_tc_long },
     *       { "the_string", &CORBA::_tc_string },
     *     };
     * \endcode
     *
     * The template parameter @a STRING_TYPE is either @c char
     * @c const @c * or @c CORBA::String_var.  The latter is only used
     * when creating @c CORBA::tk_struct or @c CORBA::tk_except
     * @c TypeCodes dynamically, such as through the TypeCodeFactory.
