The problem is that some applications may understand a certain URN; granted
most will not. This is true for any non-dereferencable URI. Even when you
have something that you can dereference, there is no guarantee that the
resource will be in a grokable format (e.g. N3 to an XML processor is not
going to be of any use to it). But then, why use URIs for predicates
anyway? All properties have to be defined somewhere, otherwise they are

Anything in the RDF M&S is going to be pre-assumed, but anything else is
just proprietary. Thus, it dosen't matter what form the alias takes on as
long as when you have reconstructed the URI it points to whatever it is
supposed to point at.

Incidentally, there are systems that parse URL (namespaces) by
dereferencing them; they tend to work, but I have not yet seen one that
uses multi-formats... maybe RDDL will help to solve that problem (point it
to XML RDF, point it to N3...)?
