DOCBOOK-APPS: Bad vertical postionning of a footer table

[Yann Dirson <ydirson@alcove.fr>]

I'm trying to put a table in the center-footer of a document.  I have
written a small customisation layer above Norm's stylesheets to do
that, but get a strange vertical positionning of the table.

This stylesheet does not discard the page numbering in outer-footer,
which makes this problem visually obvious in some documents.

I can't find where the problem comes from - my stylesheet, Norm's
stylesheet, the jadetex macros...

Does anyone see where the problem can be ?

If the problem doesn't show with your documents, you can get one at
http://ydirson.free.fr/dsssl/sample.sgml for testing.

toolchain:
- jade 1.2.1 / openjade 1.3
- docbook-dsssl 1.72
- jadetex 3.10
