I'm not sure about the Xlinking aspects, but the idea of naming and RDF 
statement (graph arc) does seem to have value as a means of identifying the 
statement with a "context" (specifically, for me: who said or assured 
it?  When?).

To recap some other threads:  full reification seems over-the-top -- simply 
having a URI with which to associate contextual information seems to be enough.

There has been some debate about using local optimizations of full 
reification.  To me, it is not clear how such optimizations would be 
represented in a serialized form of the graph model - by which I mean *any* 
serialization, not just the currently-defined serialization.

Does the URI-generation need to be standard in the sense that different 
systems must use the same mechanism for interoperability to be 
achieved?  I'm not sure.

Well, yes:  I see these issues as very related.
