Christian, I think it will look like you propose but I would include
path to QxTransformer config as property.
Like this:
--xslt-use-stylesheet=/path/to/stylesheet.xsl (main file, core)
--xslt-output-dir=/path/to/source/class
--xslt-use-config-path=/path/to/dir/containing/config.xml
In configuration we can include anything what we want including template
folder and files and others configuration properties.
