Nested, Itemized List Flows Into PDF Page Footer

I have a DocBook source with a long, nested, itemized list which
covers eight pages after converting to XSL-FO and running through fop
to pdf.  I am using the default page settings for USletter.

The list runs into the page footers on some pages.  The page the list
begins on is the first page of an appendix.

A keep-together dbfo processing instruction looks like it might help
but apparently itemized lists aren't set up that way.

Any suggestions?

Thanks.
