I agree with you as to logical software protocol stack layers.
From the "bottom", they could be:
  Transport
  Message Handler
  Transaction Manager
  Collaboration Manager
  Adapter
  Internal business app

However, to do electronic business in any practical sense
will require an integration of all of those layers, which is I
think what Stefano intends in his BSI proposal.
