This remindds me of a question I have had for some time:

Does the RM assume that all values of a given property are of the  
same type (taken from the same value set)?

Consider RDF as an opposite example: RDF literals may be untyped or  
typed but if they are typed, it is because of the type information  
comming with the literal. The type of a literal is not derived from  
the predicate of the statement that the literal is the object of.
