[Chameleon] result_fields setting for query/identify

[bartvde at xs4all.nl]

Hey Tyler,

in addition to Jason, I just wanted to mention that in Mapserver CVS
support is starting to evolve for this, so you can start filtering out
items at the service (WMS/WFS) level already in the near future.

See the following bug report:

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=950

eg:

 gml_include_items 'all'
 gml_exclude_items 'secret1,secret2'

Best regards,
Bart
