after documentation, vss-settings.xml file content is
but actual vss-settings.mdo does not define "Settings" field.
Reading such a file works only because of a bug in Modello parsing: MODELLO-152, which has been fixed in Modello 1.0.
There are 2 options for us: either change the documentation (and tell the users) to support following model (which was the initial intend IMHO):
or tweak the model and update the code to create an intermediate class for this Settings element (only useful to avoid changing the XML format)
