WM6 home.xml documentation

After discovering the configuring the WM6 home screen is nothing more than editing an XML file (/Application Data/Home/themename.home.xml on your device) I've been searching for a WM6 home.xml documentation. But as far as I can tell... there is none! Best thing I've found so far is the Homescreen guide for beginners by W411y. If anyone knows where to find a more complete documentation, please let me know!

Reverse engineering and W411y's guide helps a lot, but I want to build a Home Screen editor, and for that I'd really like to get my hands on some proper documentation...
