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

[Pat Cappelaere]

GeoRSS enabled software would store GeoRSS feeds in a WFS (or equivalent).
Users could then do spatio-temporal queries (why stop at BBOX queries!) and
keyword search based on contents of the feed.
For instance, a user could specify start/end time and/or BBOX and/or
keywords and retrieve the information based on the GeoRSS feeds that have
been collected/aggregated.

As Ron said, this is in the WFS domain with the filter specification to
retrieve the information.
