If you are using XSLT 1.0 then the type system only supports node-sets, not
node-sequences, therefore you cannot store a sorted node-sequence in a
variable.
The approach you outline would be fine for XSLT 2.0, but in 1.0 you'll have
to find some other way.

Subject: [xsl] How to sort a nodeset returned by key()?
Hi,
Short:
How can i sort a nodeset returned by key(), store it in a
variable, and still be able to compare its nodes with nodes
of the original document ?
Long:
This is a transformation of my data set to an HTML table
using rowspans.
I'm sorting my data, then I'm using a Muenchian grouping to
group rows.
My problem is that the order of my sorted node set is not the
same as the order of the nodeset returned by key(). I have
not found how to reliably distinguish the first node of the
group to output the grouping cells in the right place.
I'm using xsltproc (from libxslt)
Here is an example using Steve Muench's data from
http://www.dpawson.co.uk/xsl/sect2/N7450.html#d11343e31
If I remove this sort, the XHTML, is clean, but the table is
not sorted.
