[georss] What's next--a query API

[Allan Doyle]

I'm on the side of the "don't add any more" until things are a little  
more stable and in use. If you look at what's going on with RSS, most  
feeds are either chosen by the provider or are the result of some  
kind of query you set up through some other mechanism (generally a  
GUI/web page of some sort).

I can see it being easy enough to set a WMS to return GeoRSS with  
some MIME type hack or the same for WFS. However, I don't think it  
makes sense to add the hack for WMS/WFS return of GeoRSS into the  
GeoRSS spec.

We need more examples, running applications, and clearly we need a  
FAQ. That's where the energy needs to go.
