I think that this is

  An example view of a two-controller system::

instead of 2 controller systems.  ?

Rephrasing it as "An example view of a system with two controllers" along with other comments.
Since Saeed is sending the sf patchset which also needs port documentation, I am sending v6 of this patch along with the change log in the subfunction patchset.
