[Chameleon] Re: ExpressionBuilder and OR filter

[Yewondwossen Assefa]

Bart,

  This is a limitation on the current implementation of the filter 
encoding inside an sld. There is a bug with a better description of the 
problem in Mapserver (Bug 1694). It needs to be adressed at one point, 
hopefully in the coming weeks. Please add commnsts/suggestions through 
the bug.

Later,
