[georss] Georss extension

I would like to strongly encourage this group to consider using xAL (OASIS 
standard) for expressing additional location metadata (also known as civil 
address information). xAL has been adopted by Google for use in KML. The OGC 
is also collaborating with OASIS to develop GML schemas for xAL.

I do not want to minimize the work that Marc has done - excellent stuff.

And there are not substantial differences other than in the tags. For 
example,

geonames:countryCode>BR</geonames:countryCode>

would become

<CountryNameCode>US</CountryNameCode>

and

<geonames:adminName></geonames:adminName>

becomes

<AdministrativeAreaName>CA</AdministrativeAreaName>

I have attached an XML file that contains numerous examples of the use of 
xAL for a variety of countries. There are at least two issues that we need 
to be really concerned about - does the approach work anywhere in the world 
for any country and does the approach adhere to international (not just US) 
best practice (such as what is defined by ISO, used by other standards 
organizations) and so forth.

I know the editor of xAL, so if anyone has any questions about that 
standard, I am sure Ram would be happy to help.

Regards

Carl
