TriG production questions

Hi all,

Looking at the editor's draft of TriG a couple of questions occur to us 
at MarkLogic.

1.  Could the spec be modified to allow TriG to be a superset of 
turtle?  Specifically, could the production rules be modified to allow  
a set of triples outside of any '{'  '}' to be the same as triples in a 
default anonymous graph?  It seems that even now, the rules allow 
multiple anonymous graph productions, whose union would be the unnamed 
graph.  It would be convenient if we could dispense with these anonymous 
curly braces altogether if possible.

2.  The first two production rules

|| | graph

permit @prefix statements et. al. to be anywhere in the document.  I 
don't have any issue with that, but it was a little surprising to me, as 
these always seemed like header information to me, and it seems as 
though it might be harder to implement this way.
