Summary0005916: Semantics of "None" not clear
Description

Table 20 of Part 3 defines three possible values for a modeling rule. The "None" is not explained here. This is then further used in the implementation of state machines to give a semantics close to "static attributes of a class".

Later it is explained in the spec that "None" mades a node unavailable for instantiation and subtyping. This is then used in the definition of state machines. However, sematnics of using "None" modeling rule in interfaces is not explained. What is the official semantics of an ObjectType having a hasinterface reference to an interface having "none" variables?
