Actually I really like working with current tools but because of my
unfamiliarity it is easy to just blame the technology instead of myself.

I think this says to look up the element pointed to by the key @parentid if it
is defined, ../@id otherwise, but I am not sure I understand the [last()] -
does that mean that if both parentid and ../@id are defined, ../@id will be
used (in which case I want the reverse, first()?  or is this just defensive
programming, habit or something else?

I had expected the system (IE) to throw an error in this undefined case, but
it recovers (somewhat randomly) I guess.

Thanks again,
