In implementing the request handler, I made one change to the above.

from_input and to_output are only required where there is a payload.
Where there is no payload these are not called or required.  This
allows there to be input or output only formats.  The obvious case
would be something like a PDF handler so you could request a printed
invoice, but obviously we aren't going to allow PDF's to be used as
input!
