[cabfpub] ISO 3166-1 country codes

I've come across an edge case that I'd like to get some discussion on.


We have received a request for a customer in Kosovo, which the two
jurisdictions to which we are subject (US and UK) recognize as a sovereign
country.  However because there is still some wrangling going on in the UN,
Kosovo does not at this time have an official ISO 3166 country code.


I came across some information that the European Commission, Switzerland,
and the Deutsche Bundesbank among others are temporarily using XK as a
designator for Kosovo.  Any thought as to whether or not doing the same in a
certificate would be in compliance with Section 9.2.5 of the BRs?


9.2.5      Subject Country Name Field

Certificate Field:  subject:countryName (OID:

Required/Optional:  Optional

Contents:  If the subject:countryName field is present, then the CA SHALL
verify the country associated with the Subject in accordance with Section
11.2.5 and use its two-letter ISO 3166-1 country code.


Since XK is set aside by the ISO as user assigned, I tend to lean toward
allowing it, but I also think that we should probably decide as a group so
that we all (at least all in jurisdictions which recognize Kosovo) treat
Kosovo in a uniform fashion.  Thoughts?
