I have no trouble with this proposed name (or with just about any name
in the RDF or OWL namespaces).  I don't think that it is a significant
improvement, however.  A better improvement would be to just relabel the
datatype from being for "Internationalized Strings" to being for
"strings with language tags".

However, and this is a very big caveat, I really don't want the design
of RDF changed in response to this new datatype, as has been proposed.
If having the datatype in the rdf namespace requires a design change,
then I think that it would be much better to just have an OWL datatype
for this purpose.

I'm even becoming very worried about the requirement to avoid literals
with this datatype in RDF graphs.  So far, I'm willing to go along with
this, but the continued changes to this aspect of the proposal are
troubling to me.  In particular, the rationale for the prohibition is
completely bogus.
