Exactly 1 year to the day after abandoning the project, I am restarting it. Yay! New branch for this work will be called sydb-radd. First question: is there any difference between the 'master' and 'release-3.4.0' branches of TEI? Any significant difference? And, perhaps more importantly, how would I go about asking `git` that question? (Why, you ask? Because in order to test the Stylesheets they need to be building against some version of TEI P5. I'd like to use a local version so I don't have to wait the extra second or so it takes to download it every time I test the Stylesheets. Besides, it would be nice to know definitively which version I am testing against.)
