True. However, RDDL works reasonably well as as long as

namespace URI == URL

That is, you can put a RDDL document at a ftp or even a mailto URL if 
you care to. The problems only arise when

namespace URI == URN.

This may come down to first answering the question of how one 
resolves URNs. Then we can put RDDL documents there too. :-)

RDDL does not provide metadata for doctypes. It provides metadata for 
namespaces. Problem i may be important in and of itself, but is out 
of scope for RDDL.

Put a RDDL document at the end of whatever the URI does resolve to. 
Of course, this requires first solving the problem of how to resolve 
URIs that aren't URLs.
