For some reason, it was impossible to establish a reliable connection to Endive from any other Windows computer today, so markup work was disrupted. Greg is working on the problem. Meanwhile, I manually edited an IMT file to import categories from another document (which prompted a feature request for the IMT to be able to do this itself). We also discussed how to handle the multiple Sonnet de Courval texts, which are not exactly multiple witnesses of the same text, but close enough to be (possibly) marked up together, and how we might handle variants at the markup and display level.
