In true "design by committee" spirit, the ODX specification supports to layer an entirely different communication paradigm over its default RPC-based model: Diagnostic variables. In this model, communication with the ECU is done by reading from and writing to a set of "variables". ODX glues this communication approach on its "normal" service-oriented model by specifying a set of variables plus setter and getter services for each.
Note that, since odxtools is not concerned with communicating with ECUs directly, odxtools can only expose the required information for this, not implement this approach itself.
Besides the diagnostic variables infrastructure, this patch also adds the code to internalize the information necessary for dynamically defined messages (DYN-DEFINED-SPEC), i.e., messages which exhibit formats that are defined at runtime instead of being known a-priori.
Note that, since I don't have any data file which use either of these features, your mileage may vary.
