wfs layer not appearing in arcmap

[Neil Best]

Hi, everybody.  I have set up a WFS service at
http://geo.neiu.edu/~neiuveg/cgi-bin/trees after figuring out my PostGIS
issues and doing a test with shp2img and starting at some XML with my
browser and 'lynx -dump'.  The new mystery is why I can't see it in Arc.  I
am using Arc9.0 with the Data Interoperability Extension and I can see the
mswfs_gmap demo layers (from the HOWTO) just fine.  Maybe I am missing some
necessary metadata.  My map file is at
http://geo.neiu.edu/~neiuveg/trees.map which I basically filled in from the
HOWTO.  A fresh set of eyes looking at this would be appreciated if anyone
is so inclined.  Thanks.
