cool,
I'll add that info to the GoogleDocs chart.
And i think that should be enough info for the nit-pickers to have a

It will be neet to see how the Tiger schema compares with this.
Cheers,
Sam
p.s. the GoogleDocs chart is not yet close to being an authorative
source of info. The wiki chart is still more current..
