[protege-owl] "Abstract" class in OWL

Hi...

Is there an option to define an "abstract" class, in OWL? i.e., a class that
must not have instances... The propose of the class is only to be superclass
from others... i.e.:

Model
  Model A
  Model B
  Model C

A, B and C classes are "models", but something cannot be only "Model", must
be a model of subtype A, B or C...

Thanks!
Fernando
