In the early days [ 1,2] a was taken to be A itself. Later [9, Chap. 31 examples where Z? formed a Lie algebra, or some other algebraic relationship such as [p, X] = 1 as in quantum mechanics, or xy = qyx as in q-deformed algebras, were studied. For each subspace B one could construct a co-frame. T
