Preference for this to be solved by another namespace (e.g. Geonames,  
xAL), but featurename practices might be a stopgap.

I like RDF-A, it just happens to be illegal. Hacks still to be

Not convinced this is needed in simple. We can consider adding  
Multipoint into the GML profile.

We had decided that more than a single elevation (georss:elev) was  
unnecessary complication for GeoRSS Simple. Could be revisited.

CirclebyCenterPoint...

Common attributes...

Some of us need to finish georss.owl aka w3c neogeo, then we'd love  
to get back to GeoRSS 1.1
