Attribute Value Tuple is an Attribute Update Tuple or Attribute Read Tuple
Fundamentally, all Tuple Flows are the same in that they are all attribute value pairs. An Attribute Value Tuple constrains the attributes all be class Attributes belonging to the same Class. Within the scope of the metamodel, it seems we can inventory all tuples by their usage. Here we distinguish between tuples yielded when reading or input to an attribute update.
<subclass>.(Flow, Activity, Domain) -> Attribute Value Tuple
The Read and update action attributes in the subclasses are distinct domains (only one kind of action each), so they are not part of the superclass identifier.
