CONSTRUCT an RDF Datest

[Tara Athan]

I am working on an application of RDF and SPARQL where I would like 
construct a new RDF Dataset from the results of querying a given RDF 
dataset. From what I have read in the SPARQL 1.1 Spec, 
http://www.w3.org/TR/2013/REC-sparql11-query-20130321/#construct, it is 
only possible to CONSTRUCT a single unnamed graph, so it is not 
currently possible to CONSTRUCT even the components of an RDF dataset, 
since there is no syntax for attaching a name to the CONSTRUCTed graph.

Am I correct in my reading of the spec?
If so,
- is there/has there been/ any consideration of extending the CONSTRUCT 
syntax to datasets?
- Are there any standard practices for working around this?

Thanks, Tara
