Sorry that this comes to late, but 

  For example, Axiom's integrator gives you the answer when an answer
  exists. If one does not, it provides a proof that there is no answer.

on page 2 is simply wrong. (Apart from containing a typo) Even if read as 

  For example, Axiom's integrator gives you the answer when an answer in terms
  of elementary functions exists. If one does not, it provides a proof that
  there is no answer.

it is not true. The Risch algorithm is *not* completely implemented in Axiom,
unfortunately. It might be more complete than the ones in MMA and Maple, I
doubt that it's better than MuPAD, but boasting that it is complete is unwise,
I'm afraid.
