Feature: CTX000 - Presentation colours and textures
The rule verifies the presence of IFC entities used to assign colour, texture and other presentation appearance information to objects.
https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/concepts/Product_Shape/Product_Geometry_Colour/content.html

Scenario Outline: Check for activation - RepresentationItem attributes

Given an IfcRepresentationItem
Given Its attribute <attribute>

Then The IFC model contains information on the selected functional part

Examples:
| attribute |
| StyledByItem |
| HasColours |


Scenario: Check for activation - Styled Materials

Given an IfcRoot
Given its attribute HasAssociations
Given all referenced instances
Given its entity type is 'IfcMaterial'
Given its attribute HasRepresentation
Given its attribute Representations
Given its attribute Items
Given its entity type is 'IfcStyledItem'

Then The IFC model contains information on the selected functional part
