Hmm, so this means I'll have to detect whether or not a .TAB file has a
labels or not? I'm not sure if this would be per item, or per .TAB file
/ layer?
Also, I don't think this detection can be done in MapServer, right?
Maybe in MapBasic... Would you happen to have any ideas about that, too?
Thanks for the help!
