If you assume the RDF method, then as you know you will have the same  
problem with a host of other non-RDF specifications such as XML Schema,

e.g. which URI corresponds to xsd:int ?

Of course this is a well known issue discussed by the TAG http:// 
www.w3.org/2001/tag/issues.html#rdfmsQnameUriMapping-6 (in fact I  
raised it in 2002).

As you know, you ought not make the assumptions you have made about  
QName->URI. In the case of RDDL, you GET the document at http:// 
www.rddl.org/ and it tells you what the URI corresponding to "Nature"  
is (click on the link in the TOC).

In fact the current version of RDDL does not define the qname  
rddl:nature ... although it is defined in http://www.rddl.org/ 
20050704/ which is intended to be the new version of RDDL assuming  
folks don;t have issues.
