I am looking for 2 endorsers for the following motion to amend the BRs:


Rich Smith made the following motion and ___ and ____ endorsed it.


Add to the Baseline Requirements:


Appendix D - Country-Specific Interpretative Guidelines (Normative)

Republic of Kosovo

CAs operating in jurisdictions which have extended diplomatic recognition to
the Republic of Kosovo MAY, at their discretion, use EITHER the country code
RS for Serbia, OR in line with the European Commission (see
ntry_codes) as well as certain other governments and organizations, use the
country code XK* for the Republic of Kosovo.


* XA-XZ are designated as user-defined in ISO 3166-1 and generally SHOULD
NOT be used in trusted certificates, however this situation represents a
temporary exception given the unique diplomatic situation surrounding the
declaration of independence of the Republic of Kosovo.  It is anticipated
that as the situation resolves itself, Kosovo will either be given it's own
official ISO 3166-1 designation, or it will return to using solely the
designation assigned to Serbia.

Agreed – the CABF can decide to use ‘XK’ as its user-assigned country code
for Kosovo within the context of the BRs (perhaps, also in the context of


As Erwann recommends, the CABF should publicly document that decision – I
suggest as either an erratum or appendix to the BRs.

Nice question.

XK being one of the "user-assigned code elements", it can therefore be
freely used wherever you want, and it won't be used in any update of the
o-3166.htm#Reserved-code-elements is pretty clear on the purpose and limits
of the user-assigned codes.
Faced with such a request, I'd also tend to approve it, publicly document
the use of "XK" code to designate "Kosovo", and notify the ISO-3166/MA of
the use of this code.

EU hasn't recognized Kosovo as an independant nation, it's strange that XK
is used by the EC.

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?
