 Big changes that don't make sense to even consider for a minor release of version 1 are listed here.  Being listed here shall not be interpreted as even being likely to ever happen; this is just a collection of all the ideas that don't fit in the more realistic roadmap for version 1.
 - [ ] Allowing some simple form of `model` that makes it possible to preserve structure of the equations that will allow more efficient symbolic processing and production of executables of much smaller size.
 
+## Prototype Development and Testing
+### Deliverables
+- [ ] Feature list
+- [ ] Example models from MSL mapped against feature list
+- [ ] Library of open source unit test models matching the feature list
+- [ ] Flat Modelica v0.1 issues
+- [ ] Flat Modelica v0.2
+
+### Plan of action
+Iteratively extend the scope to be covered following these steps:
+* Select the next non-working example ("lowest hanging fruit") from MSL, or hand craft one as needed.
+* Enhance export of Flat Modelica code (functionality provided by at least one tool).
+* Enhance import of Flat Modelica code (functionality provided by all tools).
+* Map example model to roadmap items.
+* Identify newly covered language features derived from roadmap items.
+* Create unit tests for newly identified features.
+* Support newly created unit tests.
+* Capture language issues or ambiguities as they occur.
+
+The captured issues shall then be resolved by the revised Flat Modelica specification v0.2 or considered as roadmap item for later versions.
+
+### Milestones
+* MS1: Initial example working
+* MS2: 50% of MSL examples working
+* MS3: 80% of MSL examples working
+* MS4: 95% of MSL examples working
+* MS5: ~100% of MSL examples working
+* MS6: All features covered by examples/unit tests and working
+* MS7: Flat Modelica specification v0.2 defined
