CC asked me to add two features that were in the old site but hadn't yet been implemented in the new: automatic jumps to the first instance of a tagged term when following a link from a reference item to a text, and lists of texts containing reference items in the context of the text popup. I've now implemented both, but in the process I found a stack of bad xml:ids (accented chars etc.) and bad links, and had to fix all of those. I've also added a new Schematron rule to constrain ids properly. 180 minutes.
