Agreed. It seems like it would be real handy to have position() take
an argument:

 position(../s[])

and return the position of the matching items... or loosen the
restrictions on position() in a for expression, or have a different
function where you could get the position in a for expression:

for $i in ../s
 if (...) then $i/position() else ()


Thanks, Andy.
