Bingo! Now the pieces all fall together for me. This is a
specification for physical keyboards only. The levels and groups represent
not just state shiftings, but also the arrangement of glyphs on the keys
(levels vertically and groups horizontally), which is why there is a 3 level
maximum - limited room on the key. I'm not sure that there would be enough
room for 3 groups, though (visually, at least). Odd that level one and
group 1 aren't allocated more space than the others - this would more
closely conform to practice. Thanks for the pointer.
