fox:outline - Patch to get with DocBook stylesheets with FOP 0.92working

[Karsten Ohme <widerstand@t-online.de>]

Hello,

I have here a patch, which replaces the fox:outline elements with
fo:bookmarktree and it subelements. Otherwise the FO file cannot be
compiled to a PDF with Fop 0.92. Maybe can also be used in a custom
stylesheet. Is there a better fix? Is it possible to get the fop version
and branch accordingly?

Unfortunately the bookmarks in the bookmarklist of Acrobat Reader are
missing, don't know how to fix it, but at least my footnotes are
rendered correctly with fop 0.92.

Regards,
Karsten
