Comment # 2 on bug 1124078 from Imobach Gonzalez Sosa

Actually, the correct setting is file:///download/autoinst.xml instead.
Moreover, I would try to emphasize in the documentation that for that excerpt
to work you need to use autoyast2= (instead of autoyast). It is mentioned
https://doc.opensuse.org/projects/autoyast/#invoking_autoinst.options but it
might be not clear enough.

Additionally, I've found that the example won't validate (see bug 1126980 for
more details).
