/**
* The concern of the project is provide runtime values based on the model.
* <p/>
* The values in the model remain untouched but during the process of building a project notions
* like inheritance and interpolation can be added. This allows to have an entity which is useful in
* a runtime while preserving the model so that it can be marshalled and unmarshalled without being
* tainted by runtime requirements.
* <p/>
* We need to leave the model intact because we don't want the following:
* <ol>
* <li>We don't want interpolated values being written back into the model.
* <li>We don't want inherited values being written back into the model.
* </ol>
