Filter encoding - OR example with more than 2 features?

[Bart van den Eijnden (OSGIS)]

Debbie,

it depends on your Mapserver version, there was a bug that not more than 
2 conditions could be nested with And or Or. 4.8.1 should have that 
fixed for sure.

See this for more details:
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1277

Btw officially it is Or and not OR, and even more officially it should 
be ogc:Or

Best regards,
Bart
