Xiphos has never handled DisplayLevel in any way. I've looked at the wiki write-a-conf page and I'm kind of at a loss to grasp what would happen for DL > 2. DL=1, just display the entry, fine. DL=2, display all siblings at the same key level, fine. DL>=3? Do I start crawling up and down the key tree looking for stuff? It doesn't seem to me that DL>2 makes a whole lot of practical sense.
Does anyone have some code at hand that they could share, for handling the DL=2 case? Basically, given a key /a/b/c, loop through all /a/b/*. Just trim the key back to /a/b, then...what? I understand DL=2 is what must have been intended in the brief, abortive foray into genbook Bibles some years ago, so asking for Matthew/25/1 would show all of Matthew/25, but that effort clearly fell flat. I've always been uncomfortable with Xiphos' handling of genbook keys. I could use a short tutorial in code.
