Hmm. I now tried to incorporate the things into docbook-xsl and found,
that saxon/xerces and xalan/xerces work, but xsltproc still does not do,
what I want it to do. Maybe you could check this again (I guess, the
problem now is at a different place). What did I do: The docbook-xsl
stylesheets define parameters with default values. I now want to
determine a parameters default value from the content of /etc/papersize.
Therefor I used the following code:

/etc/papersize contains 
a4

So docbook-xsl should output, that it uses an A4 size for the paper
size. But I always get USletter, because $debian.libpaper.paper.type
seems to be empty. My fault or a limitation of xsltproc?
