[xquery-talk] position() and last()

[Michael Rys]

XQuery does not set the context item.

Position() and last() make the most sense in the context of XPath
expressions. 

You would need to write something like:

let $last := count($items)
return
  for $i at $position in $items
  return
    ($i, if($position = $last) then () else ",")
