and for almost all the times when they are not equivalent you can use
the following technique to get position() and last() right.
(this fails if the original context was not in document order, and there
are not enough nodes in document order to construct lists of the
required length before and after the current node.)

Note that position() of last() is correct in the fourth column, but not
in the second.
