generating OMF

[Martijn van Beers <martijn eekeek org>]

Hi,

I really didn't like creating a .omf file by hand when half of
the information in it is already in my source docbook file, so
I wrote a little xsl stylesheet to get that info out. To get
the other information at the same time, I put it in the docbook
file using namespaces.

Attached are the stylesheet, an example document and the output
from running xsltproc with those.
