Re: Problem with generating sequence ids.

XSLT 2.0 spec has introduced a function to find a
random permutation of a sequence of integers. I don't
know if this helps, but Saxon 8.4 provides
implementation of this function along with the full
XSLT specification.

Please take my word, Saxon deserves 10/10 rating in
XSLT circles.
