Interpretation of RDF reification

I've been trying to read the answer to this answer out of the RDF  
specs, and I think I've got it, but would like to make 100% certain.

If I create an RDF node that reifies the statement

   (winston, married-to, clementine)

what does that node represent? Specifically, does it represent the  
*statement* that these two are married, or does it represent the  
*marriage* relationship between them? That is, if the reifying RDF  
node is x, which of the following two statements wouldn't make sense?

   (x, start-date, 1908-09-02)
   (x, according-to, wikipedia)

I suspect the answer is that RDF nodes reifying statements really do  
represent the statements. If that's the case, what is the usual way  
of meeting the other use case in RDF?

Thanks in advance for any answers!
