I added two new packages

app-text/xmltex 	an XML parser in tex
app-text/passivetex	TeX macros for processing FO formatted xml files.

Now you can convert docbook xml's to pdf's like this:

xsltproc /usr/share/sgml/docbook/xsl/1.29/html/docbook.xsl
install.docbook >install.fo
pdfxmltex install.fo

I get a few errors if I try to convert our install.docbook from
pdfxmltex. In this cases I just hitted enter.
There are a few problems in the resulting install.pdf. The <article>
setion is not supported and the table
does not get formated correct.
Maybe that problems occure because the passivetex macros where written
for another TeX package that tetex.
I will  try to make a package for that tex system (TeX Live).
