What to do with xml:lang for triples?

Hi,

Going through the rdfs stuff, I see

	<rdfs:label xml:lang="en">comment</rdfs:label>
	<rdfs:label xml:lang="fr">commentaire</rdfs:label>

Now, RDFS is expressed on RDF and thus accessible through the RDF formal
(triple) model.  But, the RDF specs do not tell me where to store the
xml:lang attribute in the triple notation.

Within the triple representation, the only option seems
reinification of the statement and making a language statement
about the reinified label statement.  Isn't that going a bit too far
(especially as xml:lang inherits, so one would to reinify the whole
model ...)?

Anyone with suggestions?
