Konstruktorfunktionen

Die folgenden Konstruktorfunktionen für eingebaute Datentypen sind in XQuery verfügbar. Dabei ist zu beachten, dass die Semantik der Konstruktorfunktionen mit den entsprechenden cast as-Ausdrücken identisch sind, d. h., xs:TYP(xdt:anyAtomicType) korrespondiert zu dem Ausdruck cast as xs:TYP(xdt:anyAtomicType).
