It's just xsd:double[ >= 0, <= 100 ].

This post might be helpful to those who would like to assign discrete integer (or any data type) values as the range of the data type property. Type the following code in the data range expression editor:

{"0"^^xsd:int , "1"^^xsd:int , "10"^^xsd:int , "18"^^xsd:int , "2"^^xsd:int , "3"^^xsd:int , "4"^^xsd:int , "5"^^xsd:int , "6"^^xsd:int , "8"^^xsd:int}
