OK. What I meant to say is more precisely worded as:

System identifier should be always resolvable in my opinion, and this 
can't be guaranteed with URN.

So you can use URN as system identifier per XML specification. But you 
can also create HTML page containing single large Flash animation and 
this page can validate. What I wanna to say is that not everything what 
is permitted in standard is also recognized as a good usage. This even 
harder because good usage is usually evolving in time. If there will be 
some commonly deployed service able to translate URN to URL I will be 
first who will recommend you to move from URLs to URNs :-)
