   005 | Feature: LAY000 - Presentation Layer Assignment
   006 |     The rule verifies the presence of IFC entities used to assign layers (also known as, CAD layer) to collection of elements.
   007 |     This is used mainly for grouping and visibility control, and in general to organise geometry into groups that may be shown or hidden.
