Actually, that sounds like a clue! But, I can see the XML here: http://facilitylocator.vhca.org/phpadv_genxml.php?lat=37&lng=-78&radius=100
and I do see the minus signs in the markup for the longitude. Not sure why the previous validated example showed an empty XML data set (or more specifically why the minus sign was missing). But this XML looks like it's being returned ok.... Can you guys see anything off with it?
