The simplest way of declaring that a property’s range is one of a limited number of literal values

This seems like a question that should have an obvious simple answer but google has been of no help.

What is the simplest way of declaring that a property’s range is one of a limited number of literal values? As far as I understand, the following is not valid:

example:myProperty rdfs:range "yes", "no".

because "The rdfs:range of rdfs:range is the class rdfs:Class." (RDF Schema 1.1 specification).

How is this usually declared in RDF schemas? If there are alternative ways, what are their pros & cons?

Thanks for pointing me in the right direction, ASKW! 

# Declare datatype 
example:YesNo rdf:type rdfs:Datatype;
    owl:oneOf ("yes" "no").

# Use the datatype as rdfs:range
example:myProperty rdfs:range example:YesNo.

# Or else just declare the DataRange inline as anonymous class
example:myProperty rdfs:range [ owl:oneOf ("yes" "no") ].
