David Beckett's "Learn about SPARQL 1.1" presentation
(http://www.dajobe.org/talks/201105-sparql-11/) has a description of the
BINDINGS clause in the section on Federation Extensions in slides 12 and 13.
I was not aware of BINDINGS clause, so I decided to experiment with it in the
Composer's SPARQL editor:
The SPARQL editor accepts the query syntax of David Beckett's examples, but it
does not return results when executed. Is there an issue with the queries, or
does the Composer SPARQL editor not process BINDINGS?

>From presentation:
This can optionally use BINDINGS to pre-bind some variables in a SELECT:
SELECT ?a
{
?a ?b ?c .
} BINDINGS ?a {
( :value1 )
}
Returns 1 row with ?a bound to :value
This also makes SPARQL into a new syntax to build result sets with no data
source or query:
SELECT * { } BINDINGS ?var1 ?var2 {
( "var1-value1" "var2-value1" )
( "var1-value2" "var2-value2" )
}
