Today I ended up writing some XQuery that can write very thorny XSLT templates for sorting subgroups of subentries in the hierarchical index. I now have a system which can do the initial harvesting, sort most of the subgroups on their identifying morphemes (three groups are not yet sorted because it's not clear how to sort them), and spit out results in a human-readable form for checking. It's not really complicated, just incredibly detailed and picky work that takes ages to do, and even longer to debug and check.
