> agreed, though there are more performant solutions over others, 

mine in particular wasn't particularly efficient as written as it
executes ../item each time rather than using a key just to get the items
that have a chance of being in the currrent directory. That could be
fixed, but see recent thread on Re:  opinion re flexible style vs
speed :-) You could easily add some keys (especially in xslt2 where its
easier to break up the paths) but then it would look rather more like
the other solutions,
