It's mainly designed for data-intensive queries, where there is no need
to deliver the results in a particular order. In particular, putting
unordered() around a FLWR expression greatly improves the ability of the
system to do the sort of rewriting that SQL engines are good at, and
will often make it possible to exploit an index where otherwise a serial
scan (or at any rate a sort of the results) would be needed.
When you're dealing with hundreds of gigabytes of source, such things
become essential. I don't think there are strong use cases in the
typical XSLT scenario of a few megabytes.
