Artificial languages are interesting, though I always find myself longing for some index of strangeness relative to the creator's language (pick a Native American language at random; is the conlang ever going to be more different than the creator's native language than the natural language is? I doubt it.) That said, James Cameron did it right for the Na'vi language in Avatar, reportedly claiming to have out-Klingon'ed Klingon. The linguist Cameron chose to create Na'vi summarizes its structure and during the preamble of the article, his interviewer states this gem:
"...since there is already tremendous interest in the [Na'vi] language, and some less-than-accurate information about it is currently floating around online, I asked Paul [the creator] if he could write up a formal description of Na’vi as a Language Log guest post."
The problem of reference is really a set of problems in different situations. The answer to this one is I think implicit and relatively obvious. Maybe we don't know if the current king of France is bald, but we do know whether Romeo is gay or Na'vi is agglutinating.
