Not sure, but these might work:

$FmtPV['$Latitude'] = 'trim(reset(explode(',', @$FmtPV["\$Coord"])))';
$FmtPV['$Longitude'] = 'trim(end(explode(',', @$FmtPV["\$Coord"])))';

I think it's due to the GeoRSS feed generation, which is done using
the default feeds.php, which passes stuff through FmtPageName to parse
page variables, which in turn won't parse page text variables. Of
course the data could be stored as PTVs, with some kind of parallel
interface for accessing their values via PVs, but that's liable to
cause about as much work and confusion as the current (:directive:)
method. This is guess, mind.
