Definition from buildingSMART: The element type (IfcRailingType) defines a list of commonly shared property set definitions of a railing element and an optional set of product representations. It is used to define a railing specification (i.e. the specific product information, that is common to all occurrences of that product type).

NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A railing type is used to define the common properties of a certain type of railing that may be applied to many instances of that type to assign a specific style. Railing types may be exchanged without being already assigned to occurrences.

The occurrences of the IfcRailingType are represented by instances of IfcRailing.
