This section, which I wrote, was put there before we made any decision 
on what the naming mechanism of graph store means. This section should 
be considered informative, explaining how the basic semantics can be 
extended. Such extension /may/ be defined externally to this WG.

The semantics is extremely simple and does not make any assumption on 
what the "name of the graph" means. The graph name is just used as an 
indice in a family of graphs.
