Percussion pieces in SD3 kits?

All the descriptions for various drum kits for SD3 mention "full percussion" without any specifics. Does this just mean a cowbell and woodblock, or does it mean a collection of hand percussion and latin percussion. Timpanis? A list of the pieces would be VERY helpful. I would even be interested in buying an extensive "percussion collection" if SD3 offered one.

Thanks, Scook. I now realize I left out a major piece of information. I am trying to use session drummer with a set of Roland's own V-Drums as triggers. That is why I'm looking for a premade set of latin percussion. I'm assuming that Roland must have maps available to use it's own V-Drums in it's own DAW and plugins? I can't seem to find this anywhere. Using the "General MIDI Drumset map does not work well at all. It does not trigger any cymbals or hi-hats correctly. I haven't checked rimshots, etc, but I'm guessing some of those do not work either. All of the major aftermarket drum plugins seem to have built in support for all the various Roland V-Drum sets. Surely Roland has built in support for it's own drums somewhere? My alternative would be to spend a few hundred dollars on Addictive Drums or Superior Drummer to use my ROLAND drums with my ROLAND DAW and plugin? That doesn't seem right.
