A better solution is not to allow ellipsis when a zi'o value is possible,
so that zero = zi'o. Zi'o itself is a kludge universally detested, but
the notion that what is not said aloud is not said at all is much more
palatable.

Or have fewer selmaho and more converter cmavo.

pasosotu'o would be nineteen-ninety-something, not 1990s, for tu'o
= mo'ezo'e. I forget how 1990-9 is done -- is it pasosoji'i?

Maybe {su'o pi ZI'O}, {su'o fi'u zi'o} = "su'o ranging only over integer
values".

I'd prefer changing the rules for construing ellipsis, and possibly
adding UI to mark ellipsis -- you'd just add it where the unelliptized
word would occur.

This wouldn't solve the problem of what to do when you can't
elliptize a word but need it to be semantically vacuous, as
with the cmavo that turn a bridi into a sumti.
