Combined grammar (work in progress)

I'd taken a pass at a complete grammar for SPARQL 1.1

http://www.w3.org/2009/sparql/docs/sparql-grammar-11.html

and attached.

Would someone with the power please enable public access to this file?
(chairs, team).  I can't set the access control on it.

Paul - I have tried to add the current update forms as I remember them. 
  Please can you let me know what I have got wrong from where you are 
planning on going with the update doc.  I have added Steve's suggestion 
of DEFAULT as I understood it (never use absence, always use DEFAULT, to 
refer tot the default graph).

The following are the current test cases: this is a woefully incomplete 
set of tests:  more test cases very welcome.


(empty string)

LOAD <foo> INTO <blah>

LOAD <foo1> <foo2> INTO <blah>

LOAD <foo> INTO DEFAULT

LOAD <foo>

CLEAR  DEFAULT

CLEAR <g>

DROP <g>

CREATE <g>

INSERT DATA { <X> <p> 123 }

WITH <x> INSERT DATA { <X> <p> 123 }

WITH <x> INSERT DATA
{
   <X> <p> 123
   GRAPH <g> { <x1> <p1> 456 . }
}


WITH <x> INSERT DATA {
    <X> <p> 123
    GRAPH <g> { <x1> <p1> 456 . }
    GRAPH <g> {<X> <p> 123 }
}

DELETE WHERE { ?x ?p ?o }

WITH <x> DELETE WHERE { ?x ?p ?o }

DELETE WHERE { GRAPH <g> { ?x ?p ?o } }

DELETE { ?x ?p ?o } WHERE { GRAPH <g> { ?x ?p ?o } }

DELETE { ?x ?p ?o } INSERT { ?x ?p ?o } WHERE { GRAPH <g> { ?x ?p ?o } }

INSERT { ?x ?p ?o } WHERE { GRAPH <g> { ?x ?p ?o } }

CREATE <g> CLEAR <G>  LOAD <data> INTO <G> WITH <x> DELETE WHERE { ?x ?p 
?o }

CREATE <g> ; CLEAR <G> ; LOAD <data> INTO <G> ; WITH <x> DELETE WHERE { 
?x ?p ?o }
