about sreg.language and sreg.country

[Enis Soztutar]

Hi,

In SREG responses, v1.1-dratf1 of the standard states that :

openid.sreg.country:

    The End User's country of residence as specified by ISO3166
    <http://www.iso.org/iso/en/prods-services/iso3166ma/index.html>. 
openid.sreg.language:
    End User's preferred language as specified by ISO639
    <http://www.w3.org/WAI/ER/IG/ert/iso639.htm>.


However, ISO3166 is divided into 3 parts, and the first one is further 
divided into for example ISO3166-1-Alpha2 , ISO3166-1-Alpha3, 
ISO3166-1-Numeric3, ISO3166-1-English shortname, etc.
Moreover the languages in ISO639 can be represented 2-letter 3-letter or 
English/French names.

I am a little bit confused about which format will be used for sending 
these fields. Should we force a specific coding(alpha2/3, Numeric3, etc) 
to be used in the standard ?
