[Mapserver-users] Layers added but not displayed !!!

[woodbri at swoodbridge.com]

The objects with TYPE none can not be displayed as they have NO 
geometry. For example altname is just a list of TLIDs and alternate 
names for those TLIDs.

You don't have any text labels because you have not defined any in 
your mapfile under the appropriate layers.
