[OSGeo-Discuss] Options for sharing geodata symbology along with WFS?

[Jody Garnett]

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 ...
