It's part of the X.500 data model.

Every directory object can and must have only one structural object 
class, and the other classes on that object have to be auxiliary. You 
can only instantiate new objects with structural classes.

Example of an object:

structural class "car"
auxiliary class  "europeanCar"
auxiliary class  "raceCar"


europeanCar and raceCar are specializations (subclasses) of car.


Finally, FDS/RHDS do not enforce so-called "structural integrity". They 
will allow you to e.g. create an entry which contains multiple 
structural classes. OpenLDAP versions 2.1 and later prohibit this and 
there is no way to disable it, even if you try. A server should give the 
administrator the possibility of disabling structural integrity checking 
if desired...

I recommend following the rules, even if FDS doesn't enforce them.
