I guess it should also be mentioned that if you use the process in the BRs, 
you’re not really validating that the countryName is the country of the 
subscriber; in this case the countryName is the country of a domain name or IP 
address.  It’ll be a country associated with the subscriber but not necessarily 
the subscriber's home.  So I think it would be reasonable to exclude it from 
Subject Identity Information.

If we were up for some editing, I think it should be ‘Subscriber Identity 
Information’, though, not ‘Subject’.  The BRs are a bit confused about what a 
Subject might be:

… so, in a certificate with CN=www.example.com/O=Example 
<http://www.example.com/O=example> Inc./C=US, is the Subject ‘Example Inc.’, or 
‘www.example.com’, and if the second, why is ‘www.example.com’ not Subject 
Identity Information, and if the first, then what is the Subject for 
‘CN=www.example.com’?
