I see. Noting that you mentioned a redesign of the area-generating code was
on the TODO list, may I suggest that xmlroff does not attempt any splits at all
and generate an error message instead ?
That should be a QuickHack with the benefit of

a) still generating output so people can inspect *something* and
b) be a bit more clear (to users and potential developers) about what
    missing feature caused the error.
