UPDM — no ability in UPDM to define internal flows to a system or node (inside a swim lane in OV-5 or Sv-4).

There is currently no ability in UPDM to define internal flows (inform elements and data elements internal to a system or node (inside a swim lane in OV-5 or Sv-4). there should be an ability to define such things and to assoc them with the sequence flow inside a swim lane, even though these internal flows are NOT exchanges and do not show up on OV-3 and SV-6

Add text to OV-5/SV-4 to indicate that ObjectNodes can be used to show information flow between OperationalActivities and SystemFunctions.
