/**
 * Indicates that a literal has an invalid lexical value. For example: <code>"verdad"^^xsd:boolean</code> is a malformed literal because the lexical form of
 * <code>xsd:boolean</code> only allows: "true", "false", "0", or "1".
 * 
 * Not all typed literals are checked for conformance to their prescribed lexical form. The check only happens when it is necessary as part of evaluating the
 * SPARQL query. As such, this exception is most often triggered when a literal must be interpreted for use in comparison operations and type conversions.
