I misunderstood Andre's original post, sorry, my mind was thinking about the characters in the TLD, not the characters in the other labels. Oops.
It still seems weird to me to have a superset table (Japanese) as well as subset tables (Hiragana, Katakana) for the same TLD. What's the utility?

That doesn't matter, because the characters _below_ the Katakana _could_ be Han or whatever. Japanese is written in multiple scripts, so knowing that one label is only written with Katakana does not tell you whether another label might have Han characters in it. It doesn't, indeed, even tell you that there might not be a Chinese name lower in the tree, much as com today permits characters outside the ASCII range.
