I think he means reserved in the sense of the question I asked you  
about nested graphs - if graphs can't nest then it seems difficult,  
on the face of it, to have a graph that groups a set of statements  
that, say, comes from one data provider(the provenance information),  
and within it graphs that mark groups of statements in order to talk  
about evidence for them.
