The use of IfcPropertyDefinitionSet in IfcPropertyDefinitionSelect is missing.
There is no delegate class generated for IfcPropertyDefinitionSet, but for IfcPropertyDefinition it is.
I would expect something like
@XpressModel(kind="new", pattern="delegate",select="IfcPropertySetDefinitionSet")
class DelegateIfcPropertySetDefinitionSetIfcRelDefinesByProperties extends DelegateIfcRelDefinesByPropertiesIfcPropertySetDefinitionSelect {
container IfcPropertySetDefinitionSet relatingPropertyDefinition opposite aSet
}
