I recently needed to do set difference operation in a 2.0 stylesheet,
using Saxon 9 (basic version). I was a bit surprised to find that
Saxon reported, "Unknown system function except()".

The F&O spec defines this function
(http://www.w3.org/TR/xquery-operators/#func-except). Could you please
tell, why this built in function not implemented in Saxon 9.

As a workaround, I had to resort to $seq1[not(. = $seq2)] ...
