|Author's note: People too numerous to mention, from several
organizations, have supplied many of the ideas that are presented in this
document, in the course of discussions of these issues at meetings and
in private conversations. My thanks to all.
I want to mention two people in particular, Walter Schneider and David Osterman, for their help in tracking down cite-able evidence for some of the points, at a time when I was desperately scrambling to meet a deadline.
