filename is part of RFC1867 and is supplied by the browser.

As the content-type is often application/octet-stream, it can be useful 
for determining the syntax. :-)

I have a prototype that adds a form field named-graph-uri (same name as 
SPARQL query protocol, different meaning).  If it's "", absent or 
"default" it means the default graph.

Would that be what you want?  Tricky for more than one file but we could 
just restrict ourselves to one file for some text.

1/ Note that the 2 specs do apply to multipart/form-data
2/ Define it so every content-disposition: filename= means load
    as per POST for each of the SPARQL protocols.
3/ Define a form field "graph-uri"
