Structural Analysis Model

In the validation service, the types of topological representation (https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcTopologyRepresentation.htm) must be added to the valid_representation_type csv file, because for structural members (that are related to topological representations), the service gives rule errors (https://github.com/buildingSMART/ifc-gherkin-rules/blob/47b6a14/features/GEM004_Constraints-on-representation-identifiers.feature).

Vertex,topological vertex representation (with or without assigned geometry)
Edge, topological edge representation (with or without assigned geometry)
Path,topological path representation (with or without assigned geometry)
Face,topological face representation (with or without assigned geometry)
Shell, topological shell representation (with or without assigned geometry)

Also, is there any way to describe slave nodes? This information is essential in structural analysis.
