Thanks for the input, it is appreciated.

This is what I am gleaning. All of these codes seem to be found on
geneology sites, and nowhere do I find any indication that they
are commonly in use elsewhere.

What I have come up with is a "no_state" field in country.txt which I
will put in the standard demo. If it is set, the checkout forms will
not display a state/province box at all, just city and postal code.
The "multistate" order check method only requires a state/province
in the US and Canada. Though I suspect there are other countries that
might require a state, I have no authoritative knowledge that any do.

Few blame themselves until they have exhausted all other possibilities.
