Huh? Why doesn't it impress you? It's the closest thing to a standard
that exists.

Some support for SLD exists in:
 * MapServer
 * GeoServer
 * OpenLayers (and things which build on top of it)

(I'm sure others can add to this list.)

It is seperated from data (unlike mapfiles or mxd files).

It does a single job and (regardless of whether I think it does it well)
at least attempts to solve the problem in a generic way. The OpenLayers
Style/Rule/Filter framework is based on the same principles as SLD, and
in my experience, that is working well:
http://crschmidt.net/mapping/choropleth-canvas.html can be directly
mapped into SLD, so far as I can tell. 

So, I'd like to understand: What's wrong with SLD?
