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.

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.
