Enumerated Values
- Certain reserved values are automatically defined for every enumerant.
- These values are not explicitly listed in definition tables in Clause 6 since they are the same for every attribute of type ENUMERATED.
- These automatically defined values are listed in Table 4.3.
- The definitions are given in the context of a functional interface where an object is given and the function is expected to return an attribute value as exactly one enumerant value for a given object.
- Under some conditions an enumerant value cannot be returned and these special reserved values shall be used in that case.
