Re: Chewy key problem

  I feel its not possible with pure XSLT 1.0 . We need
  to take help of extension function (node-set). Below
  is the solution..

I think that's probably true, or to say the same thing another way, the
pure XSLT1 solution would be to do two passes, first do a transform that
concatenates all the text nodes into a single element or attribute, then
do a second pass that sorts on that new node. a node-set extension is a
convenience to allow that to be done in a single run of the processor.
