Depends on the application.  That puts the whole question into a different 
context (sic).

If using reification to track provenance, its not the same triple that 
appears multiple times.

If using multiple graphs (documents) for this, then I suppose I should have 
said:  applications shouldn't be sensitive to multiple instances if a 
triple in a single graph.
