Good points, Jody.

I will also point out that SLD 1.0 has been split into two in order
to make this more clear ..
SLD 1.1 really focuses on the WMS intergration
SE 1.1 isolates the information you need about styling and is much
more clearly applicable to defining *just* styles
The link for Symbology Encoding is:
- http://www.opengeospatial.org/standards/symbol
The symbology encoding document does not really define any new
concepts; it is just one document being broken into two ...

SLD is usually thought of in conjunction with WMS because you don't
see the effect of the styling until you make a map. But it
certainly applies to WFS just as well in a situation like Chris
mentions with Openlayers, where the client software is doing the
portrayal.
In addition to this:
Styled Layer Descriptor

you will also want to look at this:

Hi,
Thanks Christopher for your answer. A colleague excluded SLD by
telling
us it only applies to WMS, which, based on your comment, isn't
true. The
OGC website isn't clear on this (I guess we should read deeper).
This
would enable us to generate SLDs with uDig :-)
SLD is a language; at least some non-WMS tools can read SLD, and
style
WFS vectors according to it. (OpenLayers can do this; I'm sure that
other client software can as well.) Insofar as such a thing exists,
SLD is the primary standards based way of communicating styling
information regarding a set of data.
Some WMS servers are capable of using SLD as their style
descriptions;
I believe both MapServer and GeoServer can do this. However, other
clients can as well.
answers! :-) To my defense for this OSGeo-unrelated question,
we do
process and serve all the related geodata using OSGeo
software! ;-)
Which software?
Since you're asking.. still the same project already mentioned on
this
list: providing Canadian weather information with web maps and
standard
web services. Our (fully working) prototypes use MapFish,
OpenLayers
GDAL/OGR . (we also use other OSGeo software for other projects)
Hm, I guess my question was unclear; I was curious what software
you were
using for WMS/WFS.
GeoServer uses SLD as the primary styling configuration on the
server,
for example.
Cheers,
Alex
