| ACTION JosD: make 2 test cases using the same query but with
| different data: one without an op:dateTime triple in the input,
| and one with.

The same query is

PREFIX ical: <http://www.w3.org/2002/12/cal/ical#>
PREFIX op: <http://www.w3.org/2004/07/xpath-functions#>
SELECT ?uri ?summary ?dtstart
FROM <http://eulersharp.sourceforge.net/2004/04test/icalD001>
        (?uri ical:summary ?summary)
        (?uri ical:dtstart ?dtstart)
        (?dtstart op:dateTime-greater-than "2000-06-00T00:00:00Z")

(which I tested with N3 notation in

The data for test case 1 is

:test ical:summary "testing SPARQL".
:test ical:dtstart "2005-02-15T00:00:00Z".

(see http://eulersharp.sourceforge.net/2004/04test/icalD001.n3)

and we get back no results.

The additional data for test case 2 is the triple
{ ?A^^xsd:dateTime math:greaterThan ?B^^xsd:dateTime }
=> { ?A op:dateTime-greater-than ?B }.

(see http://eulersharp.sourceforge.net/2004/04test/icalR.n3)

and then we get back

?uri    ?summary           ?dtstart
:test   "testing SPARQL"   "2005-02-15T00:00:00Z"

(see http://eulersharp.sourceforge.net/2004/04test/icalE002.n3)
