I've never seen such. Ever, actually. Could you provide some pointers?

I mean, I see how it would work and why one would do that (just like  
relative URIs to imgs). But I've never seen it in OWL. Doesn't seem  
to be a particularly *common* idiom. As tools wouldn't have respected  
them before, by and large, since RDF absolutized, I'd be very  
surprised if people relied on that.

Well, it does seem possible that an implementation will maintain  
various serialization specific information. Or, in fact, if you are  
going through a tool anyway, you could always reserialize to the new  
location.
