Issue is on RC1.03.0 with changed description of the usage of the 2:FunctionalGroupType:

"This subtype of the OPC UA FolderType is used to structure Nodes like Properties, Parameters and
Methods according to their application (e.g. maintenance, diagnostics, condition monitoring).
Organizes References should be used when the elements are components in other parts of the
TopologyElement that the FunctionalGroup belongs to."

Machinery CS uses the 2:FunctionalGroup "Identification" with "HasProperty" References on elements which are part of the "FunctionalGroup" itself.

All figures of DI show only examples with "Organizes" References from a "FunctionalGroup" to elements. (where ever they are) (Figure 3, Figure B.1, Figure B.2, Figure B.3 "with a FunctionalGroupType Instance "Identification")

It would be nice to add in the Annex (B.4?) the Figure 12 (Example of Identification) of Machinery, to provide a usage example, how a lot of VMDA CS use the FunctionalGroup 2:Identification - and use "adapted with HasProperty References instead of Organizes".
