yes, but it only states that for *simple literals* (that are literals
without language type, IIRC). It does not seem to say anything about
literals with a language tag :-(

A test on dbpedia is not really compelling as both datatype("foo") and
datatype("foo"@en) seem to return NULL, which for the former would mean
a non-conformant implementation...
