Very good choice!

A couple of issues:

- you don't need the 'sld:' prefix in your XML elements.  The default
namespace of the SLD document should be the same as xmlns:sld
- you don't need to put quotes around the Literal values

I've attached a file which works with this WMS if you pass, along with
your GetMap request:

"SLD=3D<urlOfSldDocument>"
