*If* multiple arcs with the same (s p o) are allowed in the graph syntax, 
they would have exactly the same semantic consequences as a single such 
arc.  I can't recall which way the RDFcore WG has decided on the syntactic 
legality of this.  The original M&S talks of sets of statements, so can be 
read as disallowing multiple instances.  But my main point is that it 
doesn't really make any difference and applications shouldn't be sensitive 
to multiple instances.
