[Zope3-dev] RFC: Simplify Skinning

[Philipp von Weitershausen]

Quoting Dominik Huber <dominik.huber at perse.ch>:

Very well, I didn't think there were use cases for this. I guess there are. Thanks for
letting me know! I've given the proposal a general overhaul and ripped out this
suggestion as well. Please revise it again and let me know if you see any other issues.
