[mapserver-users] single CLASS object to label all polygons?

[Stepan Kafka]

THe simplest solution is putting the layer twice into the mapfile. The first
one with your color coding, the second one for labeling (it may be
annotation type with one class). You can switch them ON/OFF together with
using the same GROUP name for both.
