This library consists of functions that are impossible or difficult to express in terms of other functions, but rather will require a native implementation in languages like Java. In contrast, the SPL (http://spinrdf.org/spl#) namespace is reserved for functions that can be expressed entirely in terms of other SPARQL expressions and standard built-ins."^^xsd:string ;
