A good guess.  I changed the code according to your suggestion and it
reduced the processing time from ~25 to ~3 seconds.  Better but still
ridiculously slow.  When I generate the same XML document by
concatenating pre-fabricated strings, as suggested by Friedrich, the
whole process takes just 10 ms according to system.time.
