+Feature: IFC105 - Resource entities need to be referenced by rooted entity
+
+The rule verifies that resource entities are directly or indirectly related to at least one rooted entity instance by means of forward or inverse attributes.
+Resource entities are the schema classes that do not inherit from IfcRoot, typically defined in the resource layer of the schema (e.g Geometry Resource).
+
+  Scenario: Resource entities need to be referenced by rooted entity
+
+    Given a traversal over the full model originating from subtypes of IfcRoot
+    Given an entity instance
+    Given its entity type is not 'IfcRoot'
+    Then it must be referenced by an entity instance inheriting from IfcRoot directly or indirectly
