Thanks to everyone that gave comments as I was writing this. This includes David Lawyer, Deb Richardson, Daniel Barlow, Greg Ferguson, Mark Craig and other members of the <firstname.lastname@example.org> list. Some sections I got from the HOWTO Index and the sgmltools documentation. The sections on network access to CVS was partially written by Sergiusz Pawlowicz (<email@example.com>). Sections on DocBook were written by Jorge Godoy (<firstname.lastname@example.org>). A great deal of thanks to both of them for their help.
