turtle_pn_local(+Atom:atom) is semidet

True if Atom is a valid Turtle PN_LOCAL name. The PN_LOCAL name is what can follow the : in a resource. In the new Turtle, this can be anything and this function becomes meaningless. In the old turtle, PN_LOCAL is defined similar (but not equal) to an XML name. This predicate is used by rdf_save_turtle/2 to write files such that can be read by old parsers.
