Also, I don't think there's any guarantee that the resulting words will be
in the order 1,2,3 with this expression. The result of the "/" operator has
to be sorted into document order, and the relative document order of the
three constructed <word> elements, which are in different trees, is
implementation-dependent (i.e. undefined).
