[mapserver-users] dynamically added shapes and their values

[Pietro Giannini]

Dan,
I considered this solution, as well as (Steve) creating a layer for each
classification.

maybe you are right, despite I must to generate a different file for each
user-session: other garbage in tmp dir... :)

possibility of apply a style to a single feature can be a great
functionality for further releases...

what about the STYLEITEM?

thanks all
