	   Returns a new RDF::Query::Federate object for the specified $query.	The query language defaults to SPARQLP, but may be set
	   specifically by specifying either $languri or $lang, whose acceptable values are:

	     $lang: 'rdql', 'sparql11', or 'sparql'

	     $languri: 'http://www.w3.org/TR/rdf-sparql-query/', or 'http://jena.hpl.hp.com/2003/07/query/RDQL'

       "add_service ( $service_description )"
	   Adds the service described by $service_description to the query's list of data sources.

       "services"
       "algebra_fixup ( $algebra, $bridge, $base_uri, $ns )"
	   Called in the fixup method of ::Algebra classes, returns either an optimized ::Algebra object ready for execution, or undef (in which
	   case it will be prepared for execution by the ::Algebra::* class itself.
