labeling with SLDs in MapServer

[Laura Díaz]

Hi Bartje,
thanks for your answer.. i made the SLD work just changing
<Label>
<ogc:PropertyName>HOJAS10_ID 
</ogc:PropertyName>
</Label> 
for
<Label>
HOJAS10_ID 
</Label>
in the Label tag, it appears in the documentation in that way, but it does not work, at 
least in the mapserver i use 4.6.1.

yes, that is a good suggestion, it is a useful functionality
