Re: [fcrepo-user] language tags (xml:lang) in RELS-EXT ignored in triple store?

I can verify that the relationship parsing does handle language for DC
triples, but not for RELS-EXT or RELS-INT.  I'm working on a issue
branch, but I'm scheduling it for 3.6.1 since I need to evaluate the
backwards-compatibility for journaling and the web APIs.  We also
can't test this with SPO, so I'll need to revisit the integration
tests.

More specifically, org.fcrepo.server.storage.types.RelationshipTuple
needs to support the language attribute.  This in and of itself is not
a big deal internally, but I'm not sure how the serializations will
need to change. On the plus side, there are probably some (very minor)
performance improvements to be made in this part of the codebase.

Egbert, I wish I could offer my usual consolation about wiring in an
alternative module implementation that would fix it, but I dont' think
that'll work in this case.  I'll post to your issue when there's a
branch you could run from until 3.6.1 is out.
