	# more advanced stuff
	#
	# Any other CGI paramter starting with the 'rdflet_' prefix is passed down to the SPARQL query itself, and can be referred
	# into the SPARQL query as $$param_name. Multiple parameters result into a OR-ed list of value - each value can be either
	# a full qulified URI resource or a literal (with it xml:lang or rdf:datatype attached), using some N-Triples/Turtle like syntax.
	#	
	# Example:
	#
	# Given /sparql/?sparqlet_URL=<http://foo.bar/com.html>
	#
	# and the following SPARQL '&query' paramter
	#
	#       prefix dc: <http://purl.org/dc/elements/1.1/>
	#       select ?title
	#       where ( $$URL dc:title ?title )
