I don't have a vote but I'll throw in an opinion.
First of all, great discussion. I think Bill's analysis is right on.
That said, I still like container elements (key word "like"). I feel
that instance documents are slightly more intuitive and stylesheets are
more intuitive (key word "feel"). Given that "what Jim likes" is not
known to be a benefit to anyone but Jim, I certainly couldn't argue
against reversing the rule. I hope you don't though.
Regards,
Jim Wilson
