Hum, I am not so comfortable with the notion that users would be unable
to construct a graph using a SPARQL query.  Is that really the current
position?  This seems to be a pretty based feature.

Bryan,

Also fixed by removal - the section on "CONSTRUCT *" has been removed
because 
the definition doesn't work in the presence of GRAPH in the query.  The
idea was 
to return that subgraph that would give the same answers but with GRAPH
the 
query is over an RDF dataset, not a single graph.  The only alternative
I can 
think of at this late stage would be to allow "CONSTRUCT *" only if no
GRAPH 
keyword appears in the query.

and example 4:

CONSTRUCT { ?s ?p ?o } WHERE
    GRAPH ?g { ?s ?p ?o }
    { ?g dc:publisher <http://www.w3.org/> }
    { ?g dc:date ?date }
    FILTER app:myDate(?date) > "2005-02-28T00:00:00Z"^^xsd:dateTime

	Thanks again,
	Andy
