RE: [xsl] How to sort a nodeset returned by key()?

["Michael Kay" <mike@xxxxxxxxxxxx>]

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.
