Will fix that.

Could you say more here?  Reading a graph from a location does not 
automatically give it a name.  That woudl eb FROM NAMED.  This is significant 
for FROM because there can be several FROM clauses and the default graph will 
be formed using all these (e.g. the RDF merge)

FROM <graph1>
FROM <graph2>

In the example in section 9.3, the default graph is formed given the single 
IRI <http://example.org/dft.ttl> but that isn't also a naming operation.

For 9.1 and 9.3, I could add a note to say that the default graph is read from 
these locations but not named (that would be done if it were FROM NAMED).

It's a bug and will be fixed.
