With respect to the example in Section 11.1, can someone point me to
the aspect of the grammar that handles casting to a typed literal?
If these are meant as function calls, then the last line should use


and not


The full example is:

PREFIX a:      <http://www.w3.org/2000/10/annotation-ns#>
PREFIX dc:     <http://purl.org/dc/elements/1.1/>
PREFIX xsd:    <http://www.w3.org/2001/XMLSchema#>

SELECT ?annot
WHERE ( ?annot  a:annotates  <http://www.w3.org/TR/rdf-sparql-query/> )
      ( ?annot  dc:created   ?date )
  AND xsd:dateTime(?date) < xsd:dateTime("2005-01-01T00:00Z")
