3.10.8 Annex - Optional intermediate GOOSE reception objects

3.10.8.1 Introduction
IEC 61850 standards require that "logical nodes communicate with other logical nodes" (IEC 61850-7-1 Edition 2.0 2011-07
clause 9.6). That is to say, from an application viewpoint, the logical nodes (and only the logical nodes) can be understood
as being in communication with one another. As illustrated in the following figure, the receiving logical nodes directly
reference the sending logical node without an intermediate object in either the sending IED or the receiving IED. This is
accomplished in the preceding implementation model through the use of an ORG object in the receiving logical nodes that
contains a reference to the sending logical node.
