In the Quickstart Reference Server there is a node type (?) called Variant (can for example be found under CTT/Scalar/Simulation/Mass/Variant) that has a dynamic, ever changing Datatype. Is there a way to identify this type of node? If so, how?

The Variant Node. by design, has a value that could be any DataType.

The Value of the DataType Attribute is BaseDataType.

When you read a value using the Read service you get a union with a Type mask that tells you what you got in that Read, however, the next Read could return something different.
