DOCBOOK-APPS: XSL: transforming DocBook

I'm still struggling with a DocBook to foreign DTD translation.  All
earlier tips have helped me, so thanks to all of you.  What I have to
do know is the following:

Docbook has the content model:
<appendix><title>a title</title>...</appendix>
<appendix><title>a second title</title>...</appendix>
<appendix><title>a third title</title>...</appendix>

What I have to generate is:
<appendix>
<chapter><title>a title</title>...</chapter>
<chapter><title>a second title</title>...</chapter>
<chapter><title>a third title</title>...</chapter>
</appendix>

Currently I misuse a <part> in Docbook, but I'd like to avoid that.
I do find the first appendix with XSL, but I don't seem to get it
done.  Any ideas?

Jochen
