Add a convenient method to create a typed literal without lang tag
------------------------------------------------------------------
Key: JENA-83
URL: https://issues.apache.org/jira/browse/JENA-83
Project: Jena
Issue Type: Improvement
Components: Jena
Reporter: Laurent Pellegrino
Priority: Trivial
It is possible to create typed literal from the Node class by calling Node
createLiteral(String lex, String lang, RDFDatatype dtype). However, as stated
in the documentation (c.f. http://openjena.org/how-to/typedLiterals.html#lang)
"Thus for almost all typed literals there is no xml:Lang tag". It would be nice
to provide a Node createLiteral(String lex, RDFDatatype dtype) method that
delegates the call to Node createLiteral(String lex, String lang, RDFDatatype
dtype) with the right value for the lang parameter. Indeed, when I use the
existing method to create typed literal without lang tag, I put null for the
lang parameter and it works but I don't know if it is the right value (in the
jena source code it seems that an empty String is used) and whether it can
break something (the documentation give no information). Moreover it is really
annoying to have to specify the useless lang parameter when we don't need it.
