Thanks for all your efforts and time! \o/ Much appreciated!

This time I've tried it with the sources from https://github.com/SUSE/doc-sle.
Before I called it, I had to prepare a directory of all image files under
build/.tmp/img. That directory contains all the links to images/src/ (we have
separate directories for PNG and SVG).

The main file is xml/MAIN.SLEDS.xml and contains all XIncludes for different
chapters. I run the docbook script with the following arguments:

---------------------
$ /tmp/docbook-xslTNG-2.0.7/bin/docbook -xi \
   -s:xml/MAIN.SLEDS.xml -o:build/.tmp/SLES-installation.html \
   -xsl:/usr/share/xml/docbook/stylesheet/xsltng/xslt/docbook.xsl \
   media-input-base-uri=build/.tmp/img \
   mediaobject-output-base-uri=media/
No localization exists for "" or "". Using default "en".

---------------------

I don't know where this 'No localization exists for ""' comes from. Had it in
previous versions, too. ;) Of course, the result HTML is zero bytes. :)

To help debugging, would it make sense to have an option that the HTML could be
still generated? Even if there are some errors?

Although the HTML might be broken, it could give some hints where the XML
source contains some strange structures.

Thanks!
