Assefa,
Yes, it's valid. It works, but not with desired behaviour. It draws the polygons with the labels but without the Halo effect.
I forgot to put xml headers in the previous email.
<?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor version="1.0.0" xsi:schemaLocation="http://www.opengis.net/sld
StyledLayerDescriptor.xsd" xmlns="http://www.opengis.net/sld"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
I also forgot to mention that if I put <CssParameter name="font-family">Verdana</CssParameter> for example, and Verdana does not exist in my fontset, it does the labelling properly (including Halo), but it's like if mapserver gets some default values, because the size has changed and even though I change it in th e SLD, the size keeps the same.

Hi there,
Is the sld xml you are using valid? Grabbing it from this e-mail, It seems to not validate (several <PropertyName> tags). It might just a copy paste but make sure of that.
You can aslo set your map in debug mode ( DEBUG 5 for example) and check your logs to see if the xml was parsed properly and if that is the case you should also be able a tmp file of your map file after SLD was applied
regards,

Hi list,
I'm developing a program that generates some images from a WMS with a dynamic generated SLD. The problem is that I'm telling MapServer to generate some labels with Halo, to make them easy to read, using the following code:
<NamedLayer>
<Name>vinedos</Name>
<UserStyle><Name></Name><Title></Title><Abstract></Abstract>
<FeatureTypeStyle>

But when I receive the image the Halo is not applied (see attached file). My mapfile is as follows:
