In a condition, what nodes can be set as SourceNode in the SourceNode properties in BaseEventType?rnIs it only nodes with NodeClass Object since they are the SourceNode to an HasEventSource reference or can it also be nodes with NodeClass VariableType?

The SourceNode is the ConditionSource:

https://reference.opcfoundatio…..docs/3.1.9

Note 1 to entry: Typically, it will be a Variable representing a process tag (e.g. FIC101) or an Object representing a device or subsystem.

Which means it can be a Variable but not a VariableType.
