EarlyFathers goes 6 levels deep in many places; which is the limit of
ThML support.  I don't think that OSIS has a limit on tree depth.

Have you looked at the "arrows" controllability in Xiphos?  You can go
up the tree, down the tree, next element or last element.  For general
reading it works quite well.  I think that a series of lists for more
complete browsing would be a good alternate route, though.
