Wow.  That's quite a solution.  I did not know about the
node-set function, which is available in xalan as
'xalan:nodeset'.  When you had described the two-pass
solution, I was thinking about piping two XSL transforms
together (i.e., two separate stylesheets processed one
after the other).  I did not know that you could put
trees into a variable and process them with node-set.
That's very cool.

It is rather handy, saves a lot of messing around with
multiple transforms. As well as its use for indexing you
can use the same technique to split transforms into
independent phases which you can combine in different
orders as needed.

I implemented your solution, and it is a little bit
faster.  But only about 7% faster, unfortunately.  On a
sample XML file, it takes around 3000ms on average using
my old method, and about 2800ms on average using your
solution.

That is a bit poor. I was expecting more but this stuff is
always processor specific. If you let me know what
processor and version you are on I will take another go at
it. I am sure there must be a quicker solution than this.
