Re: XMLLiterals and language

IIRC, there were some changes made in the final REC of the revised 
RDF/XML spec, w.r.t the allowance and handling of xml:lang in typed 
literals [1].

With respect to the RDF Validator, note that the current version is 
based on the ARP parser found in Jena-2.0-alpha1, and I think that the 
above-mentioned changes were only integrated in Jena 2.1, so the 
validator might not handle xml:lang issues correctly.
