I'm not sure. Do you have any specific idea in mind about how this could
help ?

Ok. Something like the final Fresnel NS URI (used in the ontology files)

Agreed. And considering this, it probably makes no sense to "derive" our
intermediate tree model & syntax from an existing XML serialization of
RDF that would look somewhat like this as in the end it will be quite
different; you're right, there is little chance we can reuse an existing
XML schema.
