SPARQL imports a subset of the XPath constructor functions defined in [[[XPATH-FUNCTIONS-31]]] - [[XPATH-FUNCTIONS-31]] in section 17.1 Casting - from primitive types to primitive types. SPARQL constructors include all of the XPath - constructors for the SPARQL operand datatypes plus the - additional datatypes imposed by the RDF data model. Casting - in SPARQL is performed by calling a constructor function for the target type on an operand of - the source type.
-XPath defines only the casts from one XML Schema datatype to another. The remaining cast - is defined as follows:
