how about:

x:schnak rdfs:range aoeuii
=====>
x:schnak phil:rangeIncludes aoeuii


and maybe (if we're adopting 'range might feasibly include'
semantics):

x:schnak rdfs:range aoeuii
baoeu rdfs:subClassOf aoeuii
=====>
x:schnak phil:rangeIncludes baoeu


and then there's the owl ones:

owl:Class rdfs:subClassOf [a owl:Restriction; 
                           owl:onProperty x:schnak;
                           owl:allValuesFrom aoeuii].
=====>
x:schnak phil:rangeIncludes aoeuii.


and

owl:Class rdfs:subClassOf [a owl:Restriction; 
                           owl:onProperty x:schnak;
                           owl:someValuesFrom aoeuii].
=====>
x:schnak phil:rangeIncludes aoeuii.


Cheers,

Phil
