When ItemFlow connects (deeply) nested or inherited properties (e.g. ports or parts) we cannot uniquely identify the sources and targets in its context.
This is similar to other relationships which specialize DirectedRelationshipPropertyPath, e.g. "The Allocate stereotype
specializes DirectedRelationshipPropertyPath to enable allocations to identify their sources and targets by a multi-level path of accessible properties from context blocks for the sources and targets."
The DirectedRelationshipPropertyPath stereotype based on UML DirectedRelationship.
Stereotype <<ItemFlow>> extends UML metaclass UML4SysML::InformationFlow which specializes DirectedRelationship.
