IfcDocumentInformation has a USERDEFINED confidentiality attribute, with no guide on where we expect to see the information, should USERDEFINED be selected.
Also, STATUS does not have a USERDEFINED option, leading to inconsistency.
There is no ObjectType (or ElementType in case of element types) label attribute in IfcDocumentInformation though. Where should one store the value when USERDEFINED is provided for confidentiality attribute?
