IfcPositiveInteger is a defined type based on simple data type Integer with the additional restriction to positive integers (excluding zero).
In principle, the domain of IfcInteger is all integer numbers larger than zero. Here the number of bits used for the IfcInteger representation is unconstrained, but in practice it is implementation specific.
