By the way, you might spend an hour in frustration, including some ill-advised messing around in the guts of your system, because your browser simply will not display the TEI file when it’s hosted locally, though it will display it when it’s hosted on a server. It turns out that Chrome disables local XSL transformations for security reasons, so just use another browser. I suppose you could also put the files on a locally hosted XAMPP server.
Before I downloaded it several times, TEI Boilerplate had only 8 downloads for the current version. Can this really be?
