+Feature: LIP000 - Linear Placement
+    The rule verifies the presence of IFC entities used to position elements relative to an IfcLinearPositioningElement
+    in accordance with the ISO 19148 Linear referencing standard.
+    https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/concepts/Product_Shape/Product_Placement/Product_Linear_Placement/content.html
+
+    Scenario: Check for activation
+
+    Given an IfcProduct
+    Given its attribute ObjectPlacement
+    Given its entity type is 'IfcLinearPlacement'
+
+    Then The IFC model contains information on the selected functional part
