Suggestion from the excel document about adding the following rule "The subunit defines a namespace for its state variables, e.g. subunit “A” assigned a state variable “P@Ser202” and a subunit “B” assigned the same state variable can be distinguished as A:P@Ser202 and B:P@Ser202."

Motivation
This was discussed for L1V2.1 but was left for further consideration.

Suggested level and version

Level: L2+
