Nope, you either pass an alpha2 or an rd domain which is built by you (and in that rd structure you can set the alpha2 to your iso3166 alpha2 or "99" if unknown). > Maybe something regulatory_alpha2_hint() and > regulatory_domain_hint(). Just a thought. That's how I had it originally but decided to condense it to one routine since as you could see they pretty much do the same thing except the case where the rd is provided it calls set_regdom(). Setting it back to use two routines if fine by me too. What is better? Can we just get this merged and then we can flip it around if necessary? :) I'm tired of carrying this around.
