  The figures in this paper are indeed impressive.  I am just a
bit currious about the structure of the documents used for the
tests.  In particular, are they kind of random? (structure,
element names, depth, text content...)  Or is it always a very
simple, always identical structure?  Have those properties any
impact on the numbers in this paper?
