        In GeoRSS coordinate pairs are ordered by lat/lon and separated by
        a single white space. Given a tuple of coordinates, return a string
        GeoRSS representation.

    This allows users to define a `geometry(obj)` and/or `item_geometry(item)`
    methods on their own subclasses so that geo-referenced information may
