Instrument Trees / Yamaha XG Tree
Please note that the official XG groupings contain a few instruments in unexpected places if you're used to GM. For example, Clavinet is included with the Piano group, and Dulcimer with Chromatic Percussion. This is the way it's set in the official XG map, so I've leaving it as is.
Also note that if you're running on actual XG software or hardware, choosing an option under Drum Kits will set that staff to drum output, regardless of whether you're on channel 10 or not. So be wary if you do this and then go back and listen to the song with GM, as it will probably result in an atonal hurricane.
EDIT: Fixed a mistake in the tree; I had all the Ethnic instruments listed in Synth Effects.
