Attached is (for those interested) a small doc I wrote up. The patch is checked-in (conditional with a USE flag...).

As for integrating parts of it into main: one _could_ change the patch, so that a more generic ROOTobject class is introduced, which then could be extended in the prefix branch to contain the prefix too. However this would be quite some work on both main-trunk and prefix-trunk...

Cheers, Markus
