UAF13 — OperationalActivityEdge is a UML (Activity Diagram) Implementation of OperationalExchange - Shouldn't be in Agnostic DMM [Not Required]

p38 8.1.4 View Specifications:Operational - Operational Connectivity, Figure 8:25, p165 9.1.4 Domain Metamodel::Operational - OperationalActivityEdge Figure 9:202

The OperationalActivityEdge element is defined as :-

'A tuple that shows the flow of Resources (objects/information) between OperationalActivityActions'

Figure 8:25 shows that this element realises the OperationalExchange element (indicated by the realizedByActivityEdge role name on OperationalActivityEdge and the realizes role name on OperationalExchange).

An ActivityEdge is a particular UML method to provider a connector to join two Activity node elements on a UML Activity Diagram. This is a particular UML implementation. It should be in the UML profile for the UAF but not in an agnostic metamodel or architecture viewpoints in the DMM. How someone chooses to implement an OperationalExchange is up to them - it isn't the subject of the DMM.
