I doubt this can work in practice. {na} is consistently misused
by almost everybody, so I suspect that the rule will be eventually
generalized to order of appearance, {na} not excepted.
"na" exporting to first in the prenex is necessary for "na go'i" to
work. "na go'i" MUST be the exact negation of the "xu" sentence to allow
answering questions to work.
