  We've done that from day one.  But as Mojca remarked, there is no
subtag for Classical Latin in the registry (and in fact no subtag for
Latin at all).

  Mojca, in the mean time, using the one allocated by the Linguist list
(according to you, I didn't check) seems acceptable.  We can be overly
formal and use "la-x-cla" to emphasise that it's a private tag, but it
doesn't seem necessary.
