Juxta 1.4 was recently released, and it includes an important new feature for my work:

In addition to importing UTF-8 encoded plain text files, this new version of Juxta now supports direct import of XML source files in any well-formed schema, include TEI p4 and p5. No more preparing specialized versions of your witnesses for import into Juxta. Just import them and instantly start collating and learning things about your texts! You can configure how Juxta parses the tags it encounters. It can either include them in the reading copy, exclude them, or collate the tag type. For example if <b> changes to <i> for the same word across different witnesses, Juxta can help you detect this move. Complete details are in the online documentation on this website.

In other words, I can now compare TEI versions of “The Celestial Railroad.” I’ve been working with my research assistant to clean up the TEI on my most important versions so that I can build some comparison sets in the new version of Juxta. Exciting times!
