Stylesheets documentation build requires Oxygen licence and code
The process which creates the Stylesheets documentation depends on finding and using a script created by Oxygen, which requires the presence of a valid Oxygen key. I think this was originally done because it was quick and easy at the time, but it leaves us with a dependence on commercial software, and makes it more complex to set up and run a TEI build server. I'd like to find a way to replace this dependency if we can.
If the build script doesn't find the Oxygen bits and pieces, it doesn't build the documentation, so it's not a disaster; but documentation (especially of these complex stylesheeets) is a Good Thing, so I'd like to make it possible for everyone to generate it.
This bears on work in the Jenkins repo too; I'm currently trying an approach to building a Jenkins server as a Docker image, and the dependency on Oxygen (and hence on the TEI debian packages, which are not currently being released) is problematic.
