Summary0003600: Model class issue
Description

"In a “mixed mode”, where a single instance of an ISA95Class is represented by both a Node of NodeClass ObjectType and a Node of NodeClass Object:
 Must there be a restriction that there may exist only ONE Object (much like a singleton pattern in software engineering)? Because conversely, how would the constellation depicted in Figure 2 map back to ISA-95?
Or would one have to decide between realizing an instance of an ISA95Class as either an ObjectType or an Object?"

This item is broken out from related Mantis issue - since other items have been fixed this one can be tracked separately:

feedback

The model supports both instance and type mapping. Figure 2 describes something that could easily happen - a subtype of PersonnelClassType for Operator is created (adding appropriate properties) and then two instance are created one for unit 1 and one for Unit 2 - they would both get all of the items added in but the values of some of the properties might be different. I'm not sure what we need to do for this issue - provide an additional example? or more text?
