As it turns out there is a standard RFC 5139 for address information in XML data. That is probably a good way to go for including that kind of information in Atom feeds. More on that shortly.
Atom + GeoRSS
Out of sheer need I extended FeedWriter to support GeoRSS. While doing so I realised it lacked support for many tags from the Atom standard. I am a big fan of the IETF and their standards process. And of course I immediately thought about a full featured Atom feed writer for PHP. We’ll see how this goes. Stay tuned!
