With Protege frames, you can set minimum and maximum values for slots.

With Protege OWL 3.4 (using OWL 1.0) you have to use an enumeration or  
a custom datatype.  The custom datatype will not be handled by the  
reasoners.

With Protege OWL 4.x (using OWL 2.0) you can use datatype range  
expressions.
