[georss] Time and Space

One of the major concepts of GeoRSS is to be less geo-centric, so my  
initial reaction is to advise attaching the time period to your more  
general information nugget instead of the geometry, but I'm not sure  
if you are working with an RSS feed in the first place.

Your requirement gets at the specification of start time and  
expiration of information. Most flavors of RSS have some sort of  
'publication' date, but even that doesn't have the semantics of what  
you're talking about, so I agree your requirement isn't fulfilled  
somewhere else.

So if you're working with Atom+GeoRSS, the most universal approach  
would be to extend the Atom item with more specifics about time.
