"Country" is ambiguous

[jandrieu]

The spec includes "birthCountry" and then also includes phrases in the vocabulary definitions like "as specified by the country's official body".

I believe these are two different "countries".

Either the second use (in vocabulary) should change to "as specified by the issuer" or perhaps the credential should explicitly name the country and issuing authority (which may or may not be the birthCountry (and at least for US Permanent Resident Cards, the birth country will never be the issuing country).
