A markup language document has data entry fields corresponding to markup language nodes that are arranged in a hierarchical structure of parents having child nodes. The transmission mechanism 10 is switchable between the electrically established continuously-variable shifting state and the step-variable shifting state, by selective releasing and engaging actions of switching clutch C0 and brake B0, which are controlled by switching control means 50. Another embodiment includes a barrier material that is injected within the vascular system. With the first spin polarization layer having such a thickness, both a low magnetoresistance and a desirable TMR rate can be obtained. An annular metal tube surrounds the container and the inner wall of the tube is formed by the outer peripheral wall of the container. In embodiments of the invention, the control signals have pulse widths that operate to improve energy transfer to a desired harmonic in the harmonically rich signal.
