I think there is a misunderstanding here. "Notations" such as wee see 
them are just lexical properties of concepts that do represent classes 
in a classification schemes.
(see the presentation by Mickael Panzer on SKOSifying DDC [1])
In such a context I don't see the point of uncoupling the representation 
of the notation from the one its conceptual counterpart.
Further, Erik's solution just postpones the problem: once you've created 
your new concept for the pure notation, you still have to represent the 
code in some way. There will have to be a literal involved, whether 
plain (as for notations as prefLabels) or typed (as for notations as 

But well you're right, that's already discussing the pattern, so I 
plainly support your answer :-)
