Could you please explain what this is in
http://www.w3.org/TR/2010/WD-sparql11-query-20101014/

[27]  	BindingsClause	  ::=  	( 'BINDINGS' Var* '{' ( '(' BindingValue+ ')'
| NIL )* '}' )?
[28]  	BindingValue	  ::=  	IRIref | RDFLiteral | NumericLiteral |
BooleanLiteral | 'UNDEF'

The query spec doesn't mention it all, but it's appeared in the grammar at
the optional end of a SELECT.
