Thanks very much for pointing out those 2 tutorials and the GeoServer SLD documention.
I am actually looking for a "packaged" training and/or workshop that I can attend (either in-class or online) where I can learn best-practices for web cartography and using SLD.
I'm actually surprised that not that many individuals and organizations offer training services about SLD. Is SLD only used by the GeoServer community? Why the lack of documentation? Are there other vector styling technologies and techniques more commonly used?

use case meant for SE/SLD, that is, machine generation of
styles as opposed to manual editing).
