e3value user guide
E3value model elements have pre-defined properties that can have a value. For example, most model element have a predefined name. Appendix B lists all pre-defined properties of all model elements.
You can set and change some of the predefined properties. Other predefined properties are derived by the editor and cannot be changed by you. This is defined in appendix B and indicated in the editor
In addition to the predefined properties, you can add as many other properties to an element as you wish.
For simplicity, all our examples here use constant property values, except in section 5.11, where we give examples of computed values.
