Note: in searching for Bare-bones TEI on the TEI Consortium site just now, I discovered that someone has produced a similar profile, called ‘Bare TEI’. [Further research shows that although the page on customizations does not identify the authors, the work was done originally by Laurent Romary and later edited by Syd Bauman, Lou Burnard, and possibly also Sebastian Rahtz.] This may be worth exploring, for those seeking a minimal profile of TEI. Unfortunately, I haven’t found any usable documentation for Bare TEI, so I don’t know the design principles that govern it, and the DTD is full of undefined ghost elements (or ‘zombies’), which renders it unfortunately cumbersome in a syntax-directed editor. So for now I’m sticking with bare-bones TEI.
