[Chameleon] FILTER on a WMS layer

[Paul Spencer]

Hi Rod,

WMS layers do not support any sort of styling or filtering (by default). 
  To accomplish this, you can possibly use SLD (Styled Layer Descriptors).

If the remote WMS server supports SLD, then you can create an SLD 
document that includes an appropriate filter.  How to do this would be 
best discussed on the mapserver mailing list as there are many more 
folks there who would understand this and be able to help

Cheers

Paul
