This is an alternative to ufoNormalizer
based on XSLT. It should yield mostly the same output as ufoNormalizer.
It's been in use at Dalton Maag for several years. We're releasing it as open-source (Apache 2) in the hope to help with establishing a recommended UFO normalization format.
The test UFOs are Mutator Sans from https://github.com/LettError/mutatorSans
