[georss] proposal for country code in GeoRSS

[Marc]

Hi

I would like to propose a new country code element in GeoRSS. It would 
help feed producers to add geo information without having to specify 
exact lat/lng. Often a feed entry has a strong relationship to a country 
(or more than one country) without having an exact geographical 
position. With a country code element it would be possible to add geo 
information without having to specify lat/lng. (news, travel, job, ....)
Feed consumers at the other hand could use the country code to 
filter/group/categorize/sort feed entries.

Example :

<georss:where>
       <georss:countryCode>IT</georss:countryCode>
</georss:where>

or

<georss:where>
       <georss:countryCode>CA</georss:countryCode>
       <georss:point>45.256 -71.92</georss:point>
</georss:where>

Any comments are welcome.

Regards,

Marc
