This looks like it might be a good idea; it occurred to me too and I
remember someone mentioning it, but couldn't find the message when I
went looking for it.

Literals are slowly accruing (at least potentially) a bunch of
attributes from the XML serialisation (xml:lang, xml:base) which are
part of (properties of) the literal, but don't show up as triples.

...Although I believe an issue is outstanding to decide whether
such attributes should be directly reflected in the triple layer of the
RDF model. My personal belief is that any such reflection should be done
at the application layer, not mandated by RDF.
