SLD resquest issue with EXPRESSION parameter

[Jacolin Yves]

Hi again,

I find away to get the GetStyles XML file correctly for the last problem: I 
have to used CLASSITEM parameter in the LAYER object then use 
EXPRESSION 'UPZ.' for exemple.

I get :
<ogc:Filter>
	<ogc:PropertyIsEqualTo>
		<ogc:PropertyName>ZONE_</ogc:PropertyName>
		<ogc:Literal>UPZ.</ogc:Literal>
	</ogc:PropertyIsEqualTo>
</ogc:Filter>

Unhopefully, the "6 CLASS" issue is still present :(
