Connection ::= SEQUENCE {

                      -- The index of the connecting lane and also
                      -- the maneuver from the current lane to it
   remoteIntersection IntersectionReferenceID OPTIONAL,  
                      -- This entry is only used when the 
                      -- indicated connecting lane belongs 
                      -- to another intersection layout. This 
                      -- provides a means to create meshes of lanes
   
   -- SPAT mapping details at the stop line are:
   signalGroup        SignalGroupID OPTIONAL,    
                      -- The matching signal group send by 
                      -- the SPAT message for this lane/maneuver.

                      -- The use of some lane/maneuver and SignalGroupID

                      -- When absent, the SignalGroupID applies to all
   
   -- Movement assist details are given by:

                      -- relate this lane connection to any dynamic
